DRL question

BigBlockHead · June 10, 2005

Why are the DRL bulbs dual element? I just noticed it last night and can't think of why they would be.

I'm guessing for brightness...but its just my guess.

I think they are double filiment bulbs so that they can use one bulb for all the locations. Like my Bravada has double filiment bulbs in all of the stoplights, turnsignals, reverse lights and also the cornor illuminator light on the side of the front bumper. So maybe to cut cost they just purchase the same bulb for everything.

I always thought that one filament was for the DRL and the other one was for the perimeter lighting when you hit the unlock button.

I thought that the parking lamps were flahsed with the door locks. The roof marker lamps always flashed with the door locks on my 02. Unless they changed when GM changed the front end. Otherwise I would chalk it up to more "value" engineering from the penny pinchers.

It is for simplicity's sake alone. The taillights use the same bulb in all the locations, even though not all of them need to be dual element.

To me that is real "value" in engineering.

What would be the point of them being different bulbs?

What part number is the drl for the new chevys ??

I want to swap in ambers but haven't found a single book that lists them... and I'm too lazy to go pull it first, I guess...

No... too busy, that's it !!!

Also, is anyone else going thru tail lights like crazy ???? WTH is that ?? This is the third time I've has to swap one side or the other.... never seen such a thing !!!
