Thread: daylight running lights

What year car?

I did this on my 2002 GTP http://www.backinblackgp.com/DRL_TS_Kill.htm

Open your drivers door. Take that cover off on the side of the dash. Unplug the plug going into the silver box that has heatsink fins on it.

That will make it stay off during the day, but it will come on auto at night.


I heard that I can disable the Daytime Running Lamps (DRLs) in my Grand Prix. Why would I want to do this and how would I do it (this is not recommended)?

If you want to disable the DRLs but not the automatic headlights, unplug the voltage reducing diode in the DRL circuit. It is a large, finned object located on the outer wall on the left side under the dash. It is visible through the small access panel the you can see when the driver's door is open. If you unplug this diode, you will turn off the DRLs and not affect anything else. If you do not wish to have the automatic headlamps or DRLs active, simply pull the appropriate fuse in the fuse block located to the right of the glove box. Remember, though, that you may be eligible for a discount on your insurance premium for having and using DRLs and they are meant as a safety feature so that other drivers will see you more easily. They aren't cool, but they could save you and your shiny new GP from getting into a mishap.
