I have had my truck for about 6 months now, I have replaced the passenger
Daytime Running Light 3 times. I have noticed that every GM truck I have seen
with a DRL bulb out was always on the passenger side.
The last bulb I had to replace was an LED bulb, as I thought it would last longer
but It did not.
Anyone know of a GM bulletin for this problem ?

All help appreciated

 

Buy some electrical grease from Pep Boys or whatever your local automotive store is. I spent $2 on some and haven't had a burned out bulb since

 

Dielectric grease
Buy it at any hardware store - Ace sells the little tubes.....FYI

 

So I just put grease into bulb socket and that heals it?
I won't ask how it works I will just Do It.

Thank you very much for info.

 

yup....i see so many damn trucks with the one eye closed syndrome. always the passenger side as you described. use that grease for everything under the hood that is electrical.

 

Bought some Dielectric Silicone Grease GM part #12345579
10 bucks for a one ounce tube. Damm!

 

GM has made a new bulb that is a 14 volt bulb. It is a 4114k bulb. GM part number is 15199562.

 

Make sure you replace the bulb with the exact part # listed I believe it is 3157KX. I believe the ones you buy at std parts stores dont have the KX at the end of the part# & wasnt designed to be runned all the time. When I replaced mine I couldn't find one at the parts store so I had to go to the dealer. My truck is about 5yrs old & I have only had to replace both bulbs once.
