Where Is the Daytime Running Light Module Located?

Q: Where Is the Daytime Running Light (DRL) Module Typically Located?

A: The daytime running light (DRL) module is part of the exterior lighting system on most new cars, but not every vehicle has daytime running lights. It’s in charge of turning on the headlights and daytime running lights based on ambient light conditions.

The DRL module is typically located at the front of the vehicle or near one of the headlights. It can also be found inside the vehicle’s dashboard, in one of its fenders, or behind the front bumper. The modules won’t look the same on every vehicle equipped with daytime running lights, so be careful.

Pro Tip: The odd thing about daytime running lights is that if you look in some shop manuals, the fog lights are referred to as “daytime running lights.”

The location of the DRL module often depends on the vehicle’s make and model. For instance, if you own a 2002 Ford Explorer, you’ll find the DRL module behind the battery junction box on the inner side of the left fender. On the other hand, a 2006 Honda Civic will have the DRL module under the dashboard on the driver’s side.

Some daytime running lights are separate from the headlights and some actually use the headlight bulbs but only light them up about half as bright as when the headlights are on. There are stand-alone DRL modules and there are DRL systems that work with the body computer.

Tips on How to Access the Daytime Running Light Module

If your DRL module is inside your dash, you’ll likely need to remove a few cover panels before accessing the inside. For DRL modules behind the fender or near the headlights, searching underneath the hood is best. It’s best to check your vehicle’s user manual to find the exact location of your DRL module. It can be rather complicated to get to, so you might want to ask a professional for help if needed.
