When it comes to car safety, there are many features that drivers rely on. Airbags, seatbelts, and anti-lock brakes are just a few examples of the technologies that have been developed to keep passengers safe on the road. However, one feature that isn’t as well known is daytime running lights, or DRLs.

DRLs are exactly what they sound like – lights that are designed to help enhance visibility during daylight hours. They’re located at the front of the vehicle, and automatically turn on when the car is started. While some people might not even be aware that their car has DRLs, these lights play an important role in helping to prevent accidents on the road.

“By making your vehicle more visible to other drivers, DRLs can help reduce the likelihood of collisions, particularly during low-light conditions.”

In this article, we’ll take a closer look at what DRLs are, how they work, and why they’re so important for keeping you and your passengers safe while driving. We’ll also explore some of the different types of DRLs available, and provide tips for maintaining them to ensure optimal performance over time.

If you’ve ever wondered what those small, always-on lights at the front of your car were for, or you’re simply interested in learning more about the latest advances in automotive safety technology, read on to discover everything you need to know about DRLs.

Understanding DRL: What Are Daytime Running Lights?

Daytime running lights (DRLs) are headlights on vehicles that operate during the day. They are designed to improve road safety by making vehicles more visible to other motorists, pedestrians, and cyclists. But what does DRL mean in a car? Let’s dive into the history, types, pros and cons of DRLs, as well as popular car models with DRLs.

History of Daytime Running Lights

The first DRL was introduced in Scandinavia in 1977, followed by Canada in 1990. Since then, various countries have either required or allowed automakers to install DRLs on new vehicles. In the United States, DRLs were optional until 2014 when they became mandatory for all new light-duty vehicles under the Federal Motor Vehicle Safety Standard No.108.

Types of Daytime Running Lights

There are mainly two types of DRLs – high beam and low beam. High beam DRLs emit bright white light that can cover long distances, while low beam DRLs emit dimmer yellowish light that illuminates closer objects but consumes less energy. Other types of DRLs include LED lights, which are energy-efficient and last longer than traditional halogen bulbs, and fog lights, which enhance visibility in adverse weather conditions.

Pros and Cons of Daytime Running Lights

DRLs offer several advantages, including:

  • Improved visibility during daylight hours
  • Reduced accidents caused by insufficient lighting
  • Longer lifespan of headlight bulbs due to lower usage
  • Potential insurance discounts for vehicles equipped with DRLs

DRLs also have some drawbacks to consider:

  • Increase in fuel consumption and greenhouse gas emissions due to extra energy usage
  • Possible glare and distraction to other drivers, especially at night or in bad weather
  • Higher cost of installation for vehicles that do not come with built-in DRLs
  • May provide a false sense of security to drivers who rely solely on them for visibility

Popular Car Models with DRLs

DRLs are now standard on many new car models, from budget-friendly sedans to luxury SUVs. Here are some examples of popular car models with DRLs:

  • ToYota Camry: The Toyota Camry has been equipped with DRLs since 2002.
  • Chevrolet Silverado: The Chevrolet Silverado offers LED DRLs as standard equipment on all trims.
  • Audi Q5: The Audi Q5 comes with automatic LED daytime running lights for enhanced safety.
  • BMW X1: The BMW X1 features LED headlights and taillights that illuminate during the day.

DRLs are an important safety feature that can reduce accidents by improving vehicle visibility during daylight hours. However, they also come with some downsides such as increased energy consumption and potential glare. If you’re buying a new car, consider whether it comes equipped with DRLs or if you need to pay extra to add them. And always remember to use your headlights appropriately, regardless of whether you have DRLs or not.

Why Are DRLs Important For Safe Driving?

Increased Visibility

DRL stands for Daytime Running Lights. These lights are designed to increase the visibility of a vehicle during daylight hours, making it easier for other drivers on the road to see the car coming from farther away.

Increasing the visibility of a car is particularly important during certain times of day when sunlight can create harsh glare and reduce optical clarity. This can make the edges of objects hard to distinguish, which could lead drivers to miss objects that they would otherwise be able to see.

With DRLs turned on, cars become more visible to others on the road, providing an additional layer of safety that could help prevent accidents before they happen.

Reduced Accidents

When used properly and continuously, DRLs have been shown to reduce accidents on the road by as much as 10 percent in some cases. The reduction in accidents stems from better visibility and recognition of vehicles with DRLs turned on, especially at intersections and in rural areas where oncoming vehicles are harder to spot.

The use of daytime running lights has also been studied extensively. One study found that in countries where DRLs were required on all new vehicles, there was a decrease in left-turn accidents by about 37% compared to countries without the regulation. Another study found that pedestrians were quicker to react to vehicles with DRLs, resulting in fewer accidents or near-misses.

“Daytime running lights represent one of the few automotive features that have been proven to provide safer driving results.” – Lindsay Brook, Canadian Automobile Association (CAA)

The benefits of DRLs cannot be overstated. Not only do they improve visibility and reduce accidents, but they can also contribute to reduced costs. Vehicles with DRLs have been found to have fewer claims for car accident damage, which can lead to lower insurance premiums.

As more and more countries mandate the use of daytime running lights on vehicles, it is important for drivers everywhere to understand the importance of this safety feature.

  • DRLs increase visibility
  • DRLs help prevent accidents by making cars easier to see in all conditions
  • Studies show that DRLs reduce accidents on the road
  • Vehicles with DRLs may have reduced insurance premiums

What Does DRL Mean In A Car? Are DRLs Required By Law? What Are The Regulations?

DRL stands for Daytime Running Lights and is an automotive lighting system designed to increase visibility of a vehicle during daylight hours. While it does not replace the headlights, it increases the chances of other drivers seeing the vehicle, thus reducing the risk of accidents. But are DRLs compulsory by law?

Regulations in North America

In North America, there exists no federal law that mandates the use of daytime running lights on vehicles. However, some individual states and provinces have their regulations which require all vehicles to have their headlights on when driving during the day or required certain times of the year. For instance, California Traffic Laws mandate that headlights should be used one-half hour after sunset and until one-half hour before sunrise.

Regulations in Europe

In Europe, the legislation requires that all new passenger car models since 2011 must feature DRL. This includes both halogen bulbs and LED systems integrated into the front lamps. Before European Parliament decided to enforce this regulation, few countries already had laws mandating DRLs such as Sweden, Norway, Denmark, and Finland, among others.

Regulations in Asia

Asian countries such as China and Japan also regulate the usage of DRL in cars. In Japan, all passenger cars manufactured from April 2020 onwards were required to feature automatic turn-on lighting equipment. According to the new policy, cars that use only low beams without accompanying position lamps become illegal. Conversely, in India, there are no laws stipulating the mandatory installation of DRL on vehicles.

Exceptions to DRL Regulations

There are several exceptions to the DRL regulations around the globe. For instance, low visibility conditions such as fog, rain, or snow may require drivers to complement their DRL systems with a full headlamp system to grant adequate peripheral illumination.

Another exception relates to older cars that do not have integrated daytime running lights, which were widely installed on models produced before 2015. The owners of these vehicles can opt for retrofit installations from recognized service shops authorized to carry out any modification necessary and ensure complicity with government regulations.

“Many people today drive during the day without keeping their headlights on, hence why so many accidents occur,” -Franz Wolf, former researcher at the Swedish Road Administration

Due to lifesaving benefits offered by daylight running lights in enhancing the safety of cars on the road, it is essential for governments to consider making high-fidelity policies supporting mandatory installation, particularly in regions where they are optional. For example, legislation requiring automakers to install automatic turn-on lighting equipment would greatly improve driving experience and increase safety awareness among drivers both during night travels and in times of poor weather conditions.

How Do DRLs Work? A Quick Overview

DRL stands for Daytime Running Lights, which are lighting devices that automatically switch on when a vehicle is in operation. These lights serve as an additional safety feature by making the car more visible during daylight hours, reducing accidents and improving road safety.

Automatic DRLs

The most common type of DRLs are automatic DRLs, which turn on automatically when the engine is started without any intervention from the driver. They operate at full or reduced intensity depending on the brightness outside. When the headlights are switched on, the DRLs usually reduce their intensity to avoid distracting other drivers on the road. Automatic DRLs can be found in many modern vehicles and have become mandatory in some countries, such as Canada and European Union nations since 2011 due to the improved road safety associated with their use.

“The introduction of daytime running lights (DRL) was followed by a measurable reduction in multi-party collisions under bright conditions.” – Swedish National Road and Transport Research Institute

Manual DRLs

Manual DRLs are similar to automatic DRLs in function but require the driver to manually activate them by switching them on and off using a button, lever or knob typically located on the dashboard. Manual DRLs offer greater flexibility for those who would prefer not to run their DRLs in certain conditions, such as nighttime.


Light Emitting Diode (LED) technology has become the most popular choice for manufacturers producing DRLs due to its low cost, longer life and high efficiency. LED DRLs also come in a wide variety of shapes and sizes, allowing manufacturers to customise cars’ front-end designs while still meeting DRL brightness and coverage requirements. LED technology is a preferred choice for many manufacturers as it provides better lightning, more visibility and consumes less power than traditional incandescent bulbs.

“The high intensity of LEDs allows them to naturally provide more light output with every bullet (lumen) they eat compared to other kinds of lights, especially filament-type bulbs.” – ExtremeTech


High Intensity Discharge (HID) DRLs are an alternative to LED DRLs providing powerful beams that penetrate fog and poor weather conditions quite well. HID lighting systems use gas within a quartz glass tube or capsule to create the light, causing their increased efficiency in comparison to standard halogen headlights. One limitation of HID DRLs is that they consume more energy to produce bright beams, which can eventually affect battery life over prolonged periods of time.

“The combination of metal halide salts and xenon gas causes chemical reactions that result in brilliant white light much whiter than what most factory halogens emit…” – CARiD.com

DRLs function by automatically turning on when a vehicle is in operation during daylight hours, making cars more visible and improving road safety. Automatic DRLs are becoming mandatory in some countries due to their positive impact on reducing accidents whereas manual DRLs offer greater flexibility but require driver intervention. LED DRLs have become an industry favourite due to their low cost and longer life while HID DRLs offer powerful beams capable of penetrating poor weather conditions, even though consuming more energy to work efficiently.

How Do You Turn Off DRLs In Your Car? Here’s What You Need To Know

Disabling DRLs on Automatic Vehicles

If you have an automatic vehicle and you want to disable your Daytime Running Lights (DRLs), you should keep in mind that the process may vary depending on your car’s make and model. However, here are a few general steps:

  • Turn off your engine and headlights first.
  • Locate the fuse panel under the driver’s side dashboard or near the battery. Refer to your owner’s manual if necessary.
  • Remove the DRL fuse using pliers or your fingers. Check which number corresponds to the DRL fuse in the cover diagram or the owner’s manual.
  • Turn on the ignition switch and verify that the DRL indicator has turned off. If not, replace the fuse and look for other solutions.
“Turning off your DRLs can be risky during the daytime because it significantly reduces your visibility on the road. It might increase the likelihood of accidents especially in dark weather conditions.” -Road Safety Authority Ireland

Disabling DRLs on Manual Vehicles

The procedure for disabling the DRLs in manual vehicles is almost identical with only minor differences. Here are some easy-to-follow steps:

  • Switch off your engine and turn off any lights including the handbrake.
  • Crawl beneath the car and locate the DRL relay situated directly behind the bumper close to the front grille.
  • Disconnect the connector that comes from the headlight harness by pressing down on the latch and pulling gently away.
  • Turn on the ignition switch to check if the DRL indicator goes off. If it doesn’t, go back under the car and repeat the process.
“Before disabling your DRLs, drivers should consider carefully if this action will make them safer.” -National Highway Traffic Safety Administration (NHTSA)

While turning off your DRLs might seem like a simple solution, keep in mind that operating without DRLs could lead to potential risks while driving. It is highly recommended to consult with a professional mechanic or regulatory agency before attempting to disable your vehicle’s DRLs.

If you want to have more control over your vehicle’s lighting system, consider installing an aftermarket programmable controller for your daytime running lights. This device allows customization of light intensity, duration and visibility depending on your specific preferences.
