Last night I noticed my aftermarket fog lights weren't working...I bought my 2000 TL used with these fog lights so I don't know how they were installed, just know I have push button switch to turn it on...It may be fused, but how do i find out with area it is under the fuse box.

 

the manual shows the exact position. Some time ago, my OEM fog lights stopped working. Turned out to be because of a loose fuse.
