Does anybody know what is the bulb # for the 05 silverado, and if they make any HID kits for the fog lights?

 

i think the bulb # is 4157. un sure of HID's i know a few people were looking and never heard a reponse.

 

They are the same as the High beams, 9005

 

Same socket, but the factory bulbs are 37 watts and I believe the 9005 is 75W (or 100W). I did the diode headlight mod and replaced highs, lows and fogs with Pro Speed1 Xenons using 9005 in the fogs (singing: "I wear my sunglasses at night").

 

is it like the gmc a 9145?

 

Did you read my write up on the diode mod?



The 9005 is the same as the HB3, 9055, and 9145. 65w
The 9006 is the same as the HB4. 55w
