DRL System: Hot It Works and Replacement Guide

Reading Time: 4 minutes

Your vehicle’s automotive lights are crucial in ensuring your safety on the road. One of the most important lighting systems in your vehicle is called the daytime running light (DRL) system. So if it’s faulty, don’t think twice about replacing it. If you’re wondering what daytime running lights do and why they are important, then you’ve come to the right place.

What Are Daytime Running Lights?

Daytime running lights make your ride more visible during the day. Unlike high beam headlights, these lights aren’t there to help you see the road ahead. Instead, these lights keep your ride visible when passing through a tunnel, under a bridge, and other low-light passages.

How Does a DRL System Work?

DRL systems automatically come on when you turn on the ignition or when your ride is in motion. They rely on sensors to detect ambient daylight and determine when they activate. Daytime running lights run at a low power level compared to your high beam headlights.

DRL Light On Dash: What Does It Mean?

The DRL indicator light will usually activate once you turn on your vehicle, and it should turn off a few seconds after you remove your foot from the brake pedal.

If you notice that the DRL indicator light stays on longer than that, there’s a chance something is wrong within your DRL system. To be sure, consult your vehicle’s manual to have an idea about how your DRL system operates. On some vehicles, the DRL indicator light stays on the whole time the running lights are in use.

If you’re in the middle of the road and your car’s DRL warning light comes on, take your vehicle to an auto repair shop as soon as possible. The warning light means your vehicle’s computer has detected an issue within the system. More often than not, the problem can be traced back to bad DRL bulbs and circuits.

Are Daytime Running Lights Safe?

Low Beam Headlights vs. DRLs

Your low beam headlights and DRLs are close to each other, but that doesn’t mean that they share the same functions. 

Low beam headlights aid in road visibility, while DRLs make your vehicle more visible to other drivers. In some vehicles, these two types of automotive lights use the same bulb.

Daytime Running Light Issues

Here are some of the signs that could mean your indicator lights are faulty:

• The DRL indicator light doesn’t turn on.
• The DRL indicator light turns on, but the running lights don’t function.
• Running lights are functioning properly when your vehicle is in motion, but they don’t turn off when you turn off the ignition.

If you’re starting to experience issues with your ride’s DRL system, have your vehicle checked right away. Remember that having fully functioning automotive lights is essential for road safety.

How Much Does a Daytime Running Light Cost?

A top-notch daytime running light replacement costs around $20 to $80. Prices might vary depending on the brand you choose and other product details. Labor costs will depend on the type of vehicle you own and the rates applied in your area.

What To Consider When Looking for Daytime Running Light Replacement

There’s a plethora of daytime running light replacements available on the market, so it isn’t that hard to find one for your ride. To help you make the right choice, here are some of the things to consider when buying DRL replacements:

Quality

Your DRL system helps keep your vehicle visible during the day and ensures your safety on the road, so it’s only reasonable to get a top-notch replacement if it develops issues. Don’t settle for anything less than high-quality daytime running lights.

Compatibility

Make sure your DRL system replacement is compatible with your ride to ensure a fast and hassle-free installation. Check your vehicle manual or consult with a trusted mechanic before deciding on anything.

Brand

There are a lot of aftermarket brands that produce running lights. If you don’t have a go-to brand yet, you can read up on different brands available online. You can also go to product review pages to have an idea about other owners’ experience in installing and using the lights.

Once you’ve replaced your DRLs, make sure to follow regular maintenance checks. Having fully functioning automotive lights is essential for road safety. So aside from checking your DRLs, check the condition of other crucial automotive lights regularly as well. Have fun shopping for automotive lights and stay safe while on the road!
