What are daytime running lights?

New daytime light module Hamilton

Daytime running lights (or always-on lights) are a feature found in many late-model cars. They are bright lights that are usually built into the headlight assembly. Daytime running lights remain on whenever your engine is running and usually cannot be manually turned off. This serves as an extra visual safety indicator, helping people notice your car from afar.

The daytime running light module is a small electronic device which controls the lights. When the car turns on, the day time running lights module will activate the lights. When the car turns off, the lights will be deactivated by the day time running lights module. A properly functioning daytime running light module will prevent battery drain, as well as reduce the risk of components overheating.

Symptoms of a faulty daytime running light module:

Below are a few symptoms that indicate the need for a new daytime running light module:

Day time running lights stay on when the car is off – A faulty module will cause the daytime running lights to remain on, even when the car is turned off and the keys are removed from the ignition. This can be caused by faulty wiring or a short circuit inside the module.

Day time running lights not turning on – A faulty module can also cause the opposite to happen. The always-on lights will not turn on when you start your car. This can be also be caused by wiring problems or an open circuit inside the day time running lights module.

Day time running lights module overheating – When the daytime running light module isn’t working correctly, it can cause excess levels of heat to pass through the wiring and bulbs. This can cause serious damage to these components, meaning that more than one part will need to be replaced. When these components are overheating, you may notice a slight burning smell.
