So my cousin gave me a LED conversion kit for my fogs. I installed both into the fogs tried them, and they worked and looked beautiful. After putting the under body shields back on, I start the car and realize the drivers side fog does not work. I drove over to my cousin for another set (to swap to see what happens) I plugged in another 3 bulbs and none of them want to work.

I assume I could have blown a fuse? But is there 2 separate fuses for the fog lights (1 fog light works, other one does not)? Anyone else have any idea?

Are you using a relay kit or just connecting them straight to the fog light harness?

So there is a ballast attached, kind of like if they were hid conversion with ballasts.
Do I need a separate relay kit?

Have you switched the two bulbs to the other side to test if it's the bulb and not the wiring?

I have not, I will play around more tonight after work. Maybe even try popping the old halogen in there to see if it works.

The underhood relay/fuse box should have one for the fogs.

its the fuse if the bulb swap dont work.

Thanks guys, I will try all of the above mentioned when I am home from work. Hopefully I will have an answer later on.

It's probably the lack of a relay. I added HIDs to my fogs and ran into a ton of electrical issues including all front lights turning off, flickering, slow/fast blinking, etc. I added a 55w relay harness to the fogs and all problems went away. If the LED kit is drawing too much power this might happen to you too.

there are 2 fuses for the fogs, at least for my 2012

driver side and passenger side

It in fact was the fuse for the fog light (drivers side) that was burned out. I am just wondering what had caused it to burn out?
Everything works as it should for now (I say this coming from owning 4 German cars in the past ) just when you think all is well, a new issue arises. So for now fingers crossed, but if it ends up burning another fuse, I will definitely be purchasing a relay.

poor quality bulbs can draw non-expected amounts of current which may cause the fuse to pop
