Hello all, newly registered, but I've been visiting since my purchase back in the summer.
Had a question regarding the installation of HID's. Since the DRL are the low beam lamps would this have an effect on the HID performance or lifespan?? From what I understand the DRL are just a lower voltage signal to the headlight-would this have effects on the ballast or bulbs in the kit?
Any thoughts or comments would be welcome!! Thanks
Maybe if the weather ever breaks I will get to take some pictures--my Traverse is Black Granite with Ebony leather, 2LT with everything available, roof, nav, rear ent. all the bells and whisles!! I've got it debadged with black bowties so far!!

HIDs are not used as DRLs. If the car has HIDs then the DRL function is done through the high beams.

I think he meant adding aftermarket HIDs...

Im going to say that yes it does affect them....

I know that on the Trailblazers- the low beam is also the DRL.
People on the Trailblazer/Envoy forum who have installed HIDs- soon come back with complaints like--- My HIDs flicker. Or Ballast burned out...
I think it was because the DRL is a low voltage piecewise signal (you know it chops the 12 volts signal in certain places- so the voltage never reaches 12 but stays at lets say 5 volts)...
Anyways--- this low voltage causes the ballast to flicker--- come on and off or do funny stuff....

The fix is to disable the DRL....
On the trailblazer forum--- there was a guy who created- and sold what was called a DRL killer...
something you bought from him- installed- and away went your DRL's- and now you had happy HID's....

I dont know if his DRL killer was specifically built for the Trailblazer/Envoy DRL's circuit- or if it can be applied to other cars...

I believe we can disable DRL by pulling out a fuse.
