I have a 06 screw that did not come with foglights. The previous owner bought a bumper off a wrecked 07 I believe (it's the round lights) and installed fog lights hisself. He has it ran to the battery and a relay I believe. Now his power wire for the passenger side foglight splices into the power for the driver side. Anywho the fog lights work perfect but today I put led bulbs in them and now only one works. The bulbs are fine because both lights will work on the driver side but neither on the passenger. Any input on how to get the other one to work? Maybe I need a smaller fuse? Im not sure I suck at electrical work.

 

Go get volt meter and check for power on the passenger side . If you got power , reverse the polarity hook up , led's only work one way . Also if no power check your connections. . It's not that hard. Good luck

 

Like what angel said, check if you're getting power. And if you are getting power, just flip the bulb and it should work.

 

I know bc polarity they only work one way but the issue is the bulb can only plug in one way bc it's a fog light 9005 bulb it has a 90 degree angle. I know the socket has power bc a halogen bulb works fine. I think I'll have to mess with wiring. I just don't know what.

 

I cut the power and ground wires and reversed those and it works perfectly now. I knew I couldn't change the plug bc it only goes in one way, didn't think to cut the wires. Thanks for the help guys.
