Normal. Mine doesn't illuminate. Nor does the factory fog light switch from what I can tell. Which I find more curious than the dimmer. The only time the fog light switch illuminates is when I have it pressed in to turn on the fog lights. And then it illuminates with an amber color and not the blue that everything else is. I haven't received any response from anyone with the factory fog lights to confirm if this is normal or if I may have not wired in a connection correctly when I installed the kit.
