What is the Daytime Running Lamp Module all about?

It can be difficult to identify oncoming traffic in certain conditions like fog, light rain, snow, and even on very sunny days with blinding glare. A system developed in the 80’s to automatically turn on a low-intensity light whenever a vehicle is in motion is known as daytime running lights, or DRL’s. These lights use reduced intensity high beam headlights, regular or reduced intensity low beam headlights, or marker lights for more prominence when driving. Lawmakers in Canada and in places overseas have implemented daytime running lights as law for all new vehicles since the 90’s, yet US lawmakers have not done so. Some automakers such as GM have voluntarily put DRL’s in their vehicles as an added safety feature.

The running lights are not the same as automatic headlights that turn on in dim lighting conditions, and typically DRL’s cannot be overridden. The DRL’s are controlled by the daytime running lamp module that receives a signal from the ignition to turn the running lights on when the vehicle is started. If the module short circuits internally the running lights may stay on indefinitely even with the ignition off, or they may not come on at all. If the wiring corrodes or breaks, the daytime running lights may not operate or operate intermittently.
