Have you ever noticed some cars driving with lights on during the day? Those are called daytime running lights (DRLs), and they serve an important purpose. Although DRLs have been around for several decades, many drivers still don’t know about their benefits or why they’re necessary.
DRLs are a safety feature designed to increase the visibility of vehicles on the road, especially during low light or poor weather conditions. They make it easier for pedestrians, cyclists, and other drivers to see your car from a distance, reducing the risk of accidents. Some studies suggest that DRLs can lower crash rates by up to 10% or more. This is particularly true for older model cars without automatic headlights and those driven in countries with shorter daylight hours.
In this article, we’ll explore what DRLs are, how they work, and why they’re important. We’ll also look at the different types of DRLs available and whether they’re required by law. By the end of this post, you should have a better understanding of DRLs and why they’re essential for any modern vehicle. So, let’s get started!
Definition Of DRL
If you have noticed a bright light on the front of your car that is constantly illuminated, even when the headlights are not turned on, then you are seeing the Daytime Running Lights or DRLs. These lights are an important part of modern vehicles and they serve multiple functions.
What Are DRLs?
DRLs are special lighting systems that help increase visibility during the daytime hours when the sun is out. They use lower intensity bulbs than traditional headlights and work in conjunction with them to provide better illumination.
The concept of DRLs was first introduced in northern European countries where there would be shorter days due to low sunlight, and it proved to be very effective in reducing accidents. It found its way into Canada by 1989 as one of the road safety measures and became mandatory for all new cars sold in Canada from 1990. Many other countries followed suit, and now, the majority of new cars come equipped with these safety features.
How Do DRLs Work?
DRLs work via a small control module that senses ambient light levels outside the vehicle. If the sensor detects low levels of external light (such as when driving during the day), the system turns on the DRLs automatically. These lights will then remain on until the sensor detects high enough ambient light levels or the driver manually activates the headlight switch. Most cars’ automatic headlights function overrides DRL’s operation such that when the front darkness sensors activate when entering a tunnel or turning on the actuators at night time–the DRLs turn off and actual headlights take over.
DRLs consume less energy compared to the regular headlights as they utilize LED indicators, which last longer and consume less power. Thus, they do not result in any significant impact on fuel economy.
Why Are DRLs Important?
DRLs are important for various reasons, with the most vital being that they improve visibility and make it easier for other drivers to see your vehicle in daylight conditions. Research has found out that using DRLs during daytime can reduce multiple-car collision rates by 10-15%, and also significantly decrease pedestrian fatalities.1
Apart from safety reasons, manufacturers now use these lights as a signature branding identifier. Many car makers highlight their vehicle designs with notable LED DRL light patterns that help recognize them quickly.
Types of DRLs
There are two primary types of Daytime Running Lights: High beam-based systems and Dedicated DRL Systems.
- High Beam-Based Systems: These work by using high beams at low intensity levels. They require special blinker lamps or control units that we well-coordinated with headlights and fog lamps.
- Dedicated DRL Systems: These feature a separate assembly comprising LEDs that run in distinct housings within the lower bumper.
“Reducing deaths and serious injuries on our roads is one of our priorities. Requiring newer cars to have electronic stability control and daytime running lights will go some way towards this.” -Bernard Hogan-Howe (Former Head of Metropolitan Police Service (MPS), UK)Overall, DRLs are an effective technology that enhances road safety when used correctly. Keep your Daytime Running Lights illuminated while driving for safer journeys! _______________________ Sources: 1 de León-Cabrera et al (2019): Pedestrian collisions in Colombian roads before and after the implementation of daylight running light in cars, International Journal of Injury Control and Safety Promotion.
History Of DRL
DRL stands for “Daytime Running Lights”. These lights are specially designed to be used during the day to improve road safety by providing extra visibility. The idea of using low-intensity running lights goes back several decades, but it wasn’t until relatively recently that they became mandatory in many countries.
Development of DRLs
The development and testing of DRL technology began in the early 1970s with research conducted by Volvo. However, it wasn’t until the late 1980s and early 1990s when automakers started incorporating them as standard equipment. This adoption was mainly due to Canada’s regulations requiring all cars sold there to have DRLs beginning in 1990.
In the United States, where rules regarding DRL use were less strict, carmakers first added DRLs as optional features on higher-end models. They also developed different versions of DRLs to cater to consumer preferences or regulations in different regions. For example, some manufacturers opted for LED lighting while others chose high-output halogen bulbs.
First Use of DRLs
Sweden was the first country to mandate daytime running lights, which became compulsory in 1977. Norway made them obligatory in 1986, and Denmark followed suit a year later. In North America, Canada was the first to make DRLs mandatory beginning in 1990. European Union (EU) legislation requires new types of passenger cars and light commercial vehicles to have DRLs since February 2011. The EU regulation applies to passenger vehicles specifically.
Impact of DRLs on Road Safety
The goal of DRLs has always been to improve visibility under daylight conditions on roads, thereby reducing accidents. Studies suggest that DRLs can significantly improve visibility and reduce collisions during the day. One of the most notable examples is a study conducted by Transport Canada that showed a 5% decrease in daytime fatalities after the introduction of DRLs was required for all new vehicles. Other research also indicates that DRL reduces the number of pedestrian collision involving automobiles.
Evolution of DRL Technology
DRL technology has continued to evolve since its adoption. For instance, modern LED-based DRLs are up to ten times more efficient than halogen bulbs which makes them energy-efficient and eco-friendly. They have a longer lifespan as well, due to their solid-state design. Some manufacturers now offer adaptive DRL technology that adjusts automatically to ambient conditions or changes in weather, providing better lighting when needed. The advancement in LED technology has allowed automakers to develop dynamic turn signals, a feature that has been hailed by car enthusiasts and safety proponents alike. These lights not only look cool but keep drivers informed of the direction they intend to take while also notifying pedestrians what the cars are going to do next.
“The use of dedicated daytime running lamps (DRLs) on passenger vehicles decreases crash rates” – National Highway Traffic Safety Administration
Making Daytime Running Lights mandatory for new cars sold worldwide has improved road safety and contributed to reducing traffic incidents during daylight hours. Their implementation shows how advances in technology can translate into positive safety impacts without compromising efficacy or efficiency.
Benefits Of DRL
Enhancement of Road Safety
DRL stands for Daytime Running Lights and it refers to the lights on the front of a vehicle that are used during daylight hours. The primary benefit of DRL is that they enhance road safety in several ways.
Firstly, DRL allows other drivers to see your car from a greater distance away which makes it easier to avoid collisions. It also increases visibility from different angles as well. Therefore, using DRL can reduce accidents considerably while driving.
A study conducted by the National Highway Traffic Safety Administration (NHTSA) revealed that vehicles with DRL have a 10% lower accident rate when compared to those without them.
“Given their effectiveness, DRL could be considered one of the most important safety innovations introduced in recent times,” says Wheels24, South Africa’s largest online motoring magazine.
Increase in Visibility
The use of DRL enhances visibility for not only drivers but also pedestrians and cyclists too. When drivers use DRLs, it is easy for pedestrians or cyclists to spot due to the increase in brightness, especially when pulling out of junctions, zebra crossings, or roundabouts.
A clear example we can consider here is the effect of light on our vision at night time. Drivers who fail to turn on headlights create dangerous situations for everyone around because they significantly limit how quickly and efficiently people can react. Similarly, if you forget to shut off your high beam while driving through an intersection, this puts other motorists at risk of getting into an accident because glare may impair their vision momentarily.
“Studies show that DRL improves visibility and recognition of vehicles, right-of-way rule compliance, and pedestrian conspicuity,” according to NHTSA.
Reduction in Accidents
DRL can help drivers avoid accidents by making them more visible to other drivers and pedestrians on the road. This reduced accident rate happens because drivers are allowed extra time to react, thanks to DRL; leading to decreased crash severity if an impact does occur.
The Canadian government believes wholeheartedly in the benefits of DRLs that they made it mandatory since 1989 for all new passenger vehicles manufactured or imported after December 1st, 1989, to have DRL installed on their front lighting systems.
“DRL laws save lives and reduce injuries, as NHTSA also found that Sweden saw a nearly 20% reduction in multiple-vehicle daytime crashes after adopting a law requiring vehicles to use low-beam headlights during daylight hours,” states Forbes Magazine.To conclude, using DRL is not only about car light aesthetics but also holds immense importance concerning safety. It has been proven over and again that DRL leads to fewer collisions and fatalities, making roads safer for everyone. Driving with DRL brings peace of mind, given the security and assurance it provides throughout our journeys. Stay safe!
DRL Laws By State
State DRL Requirements
Daytime running lights (DRLs) are a vital component of vehicle safety, improving visibility on the road during daylight hours. All U.S.-manufactured vehicles have been required to include DRLs since 1996, and as of 2021, thirty-two states also require that all drivers use their headlights while driving during daylight hours.
Certain states mandate year-round use of DRLs for all vehicles, while others only require them during certain months or times of day. In addition, some states may require specific types of lighting equipment, such as high-beam headlamps or LED lights. To ensure compliance with these laws, it is essential to know your state’s specific requirements.
Penalties for Non-compliance
Failing to comply with your state’s DRL laws could result in fines and other legal consequences. The severity of the penalties will vary based on the state and the circumstances surrounding the violation. For example, some states may assess monetary penalties ranging from $50 to over $250, while others may impose license suspensions or even jail time.
Beyond the legal implications, not using your DRLs can put you, your passengers, and other motorists at risk by decreasing visibility and increasing the likelihood of an accident. Therefore, it is crucial to stay informed about the timing, placement, and maintenance of DRLs in your region, to keep yourself and those around you safe on the roads.
“The point of daytime running lights is to increase visibility during the day, which can lower fatalities due to accidents where one driver was invisible to another.” – Aimee Picchi
Understanding DRL laws by state is critical for ensuring your safety and avoiding legal penalties. The specific requirements for the use of DRLs can vary widely from state to state, so it is important to research your home state’s laws and regulations in detail. Remember, using DRLs improves visibility on the road and helps prevent accidents – don’t let yourself or others fall victim to poor lighting conditions.
How To Turn On/Off DRL
DRL stands for Daytime Running Lights, which are standard headlights that remain on even during daylight hours. This feature was first introduced in cars and light trucks in Scandinavia in the 1970s as a safety measure to improve visibility and prevent accidents.
If you would like to turn off or disable your car’s DRLs, there are several methods you can try. Depending on your vehicle make and model, automatic activation of DRLs may be enabled by default when the engine is started. Most commonly, DRLs are controlled through an electronic module called a Body Control Module (BCM).
Automatic Activation of DRLs
On many vehicles, including most newer models, DRLs are set to activate automatically as soon as the car’s ignition is switched on. The lights will remain on until the engine is turned off, regardless of whether it is daytime or nighttime.
To check if your car’s DRLs are on automatically, simply turn the key in the ignition and observe the headlights. If they switch on automatically, then your car has this feature enabled.
Manual Control of DRLs
In some cases, car manufacturers provide drivers with the option to manually turn their DRLs on or off using a control switch or menu setting. Typically, this control switch is placed on or near the headlight controls, depending on the design of the vehicle.
Consult your owner’s manual or contact your dealership if you are unsure whether your car has this option. If it does, follow the instructions provided to activate or deactivate your Daytime Running Lights.
If you want to completely disable your car’s DRLs, you may be able to do so via the BCM. However, it’s important to note that doing this might not be legal in all jurisdictions, as DRLs are a mandatory safety feature in many countries.
Consult with your dealership or local mechanic before making any changes to your car’s lighting system. They can advise you on whether disabling your Daytime Running Lights is legal and safe for your use case.
Common Issues with DRL Activation
In some cases, DRLs may malfunction and fail to activate when they should, or remain activated even at night. This could be due to faulty wiring, damaged electronic modules or overheated bulbs.
If you notice any issues with your car’s daytime running lights, such as flickering, dimming or inconsistent operation, have them inspected by a qualified auto technician immediately.
“The use of Daytime Running Lights has been shown to reduce accidents involving pedestrians and other vulnerable road users, particularly during times of low visibility.” – Road Safety Authority Ireland
Common DRL Problems And Solutions
DRLs Not Working
DRL or “daytime running lights” are an important safety feature of modern vehicles. They increase visibility during daytime driving by keeping the headlights on at a low power level. If your DRLs are not working, there are several reasons why this may be happening.
- The first thing to check is the DRL fuse. The fuse box location and layout varies between vehicles, so consult your owner’s manual for specific instructions.
- If the fuse is intact, the next step is to check the bulbs. Burnt-out bulbs will need to be replaced with new ones.
- In some cases, faulty wiring may be causing the issue. This can be more difficult to diagnose and fix, so it’s best to take your car into a mechanic or auto electrician.
“When replacing any lighting, always seek professional assistance from your local dealer.” -Tirecraft Auto Centers
If your DRLs are flickering, the reason may be due to one of these common problems:
- A loose connection or faulty wire can interrupt the electrical current to the bulb, causing it to flicker on and off.
- Faulty alternators can cause voltage spikes that lead to the flickering of lights in the vehicle.
- An issue with the battery or charging system could also cause voltage fluctuations and affect the function of the DRLs.
To fix these issues, it’s recommended that you visit your local automotive service center as soon as possible, as they have the necessary tools and expertise to identify and repair any electrical issues.
“These flickering lights are often the result of an intermittent electrical fault which can only be identified with specialist equipment.” -The RAC
