Fuse # to the Fog light's
 

I have HID's on my FR-S Foglights. the Left side is on but not the right side. I'm thinking it's probably a fuse issue or a ballast. I was thinking of checking on the Fuse first before going back to my guy who installed it for me which is covered under warranty. I just don't want to bother the guy with fixing my fog light issue for the third time lol.

If the fuse is for both fog lights, which I can only assume it is, then if one of them is working, the fuse is not the problem. Do you get alot of fog in Westchester?

sometimes yes, but I like to turn them on just for the show because my fog lights are 4.5K HID's which is not that bright it just makes the car stand out really good. so if one of the fog lights is on and the other side is not, it's perhaps the ballast. Sigh:: I really hate bringing it back to these guys again for the third time.. It make's me feel like i'm annoying them lol

Does it use one fuse or two? On the BRZ there are two fuses, one for each side. If there is only 1 fuse then it is either the wiring, ballast, or bulb that is bad. It's easy to test with a voltmeter.
