I purchased LED foglights and I have a strange problem. Both LED bulbs will work on the driver side but neither will work on the passenger side. Stock fog bulbs will work in both locations. Anyone else heard of this problem?

Thanks

sound like a wiring harness problem, the male or female connection on the passenger side must be bad or slightly out of contact for the LED.

you might need to get a new wiring harness, but check and see if one of the two contact pins are bent out of place or pushed in too far.

 

try switching the bulbs around.. kinda hard to explain..

 

I had the same problem with my LED license plate bulb. did this, working great now..

 

I dont see where the pins are bent and everything looks fine. Both bulbs are working fine in the driver side socket but neither are working in the pass. socket so its not a bulb problem. I tried cleaning the socket with electrical connection cleaner and even used dialectric grease on the connection. If it is the connector the only way Im going to improve it is to solder in a new pigtail. The only other things I can think of is a weak ground on that side of the harness or maybe a relay but I dont even know if the fogs are relayed. I think Im going to have to break out the multimeter this weekend and take some readings. Thanks for the ideas.

It's a sign...go HID!

 

This sohould be an easy fix. The same thing happen to me, but with my HID fogs. Incandescent bulbs light up now matter how you connect them, led's and hid's don't. Pull out the pins going into the bulb socket and swap them. That way the positive lead is going to the positive on the led and the same for ground.

 

Ill give the pos / neg swap a try.

Thanks

try to sand it off the connectors if possible.

 

hey you should post pics of the lights i wanna see how led fogs look like

 

Looks bright, does not come close to a decent amount of light output thats usable. HID kit is the only thing i would use.

 

Type S was right on the money. The pos and neg leads were reversed on the pass. side from the drivers. Switched them over and it worked fine. Will try to get pictures up but I am on the road for the next couple of days.

Thanks for the help

post some pics, btw, how many LED is the light bulb? 18? 68?
