Both of mine are burnt out and I noticed there are 2 filaments... someone used the wrong bulb... I read a TSB (see below) that recommends an updated bulb, but I feel I may a swell use an LED. Is there a recommended source? part #?

@OneofFew, not necessarily the wrong bulb. The owner's manual and bulb charts show the dual-filament bulb is the one to use -- for DRLs, I have no idea why. Always wondered about that, one of life's little mysteries.

I got ride of mine and put switch backs in my turn signal's.
Whoa welcome back buddy:happy107:



Side note, use 4114 halogen or led. Can be found at any local parts store. Learned the hard way with my Silverado, went through 2 pairs of 3157 LEDs when I finally did some research and found out the correct bulb.
