Thanks Chromenut.
From your answer, I'm assuming they are on, but there is no headlamp in the housing currently.
I'm not sure if the car came with them or without them.
I bought the car from a private party who wasn't the original owner.
I'm woefully inept when it comes to car related acronyms, so I don't know what MFS or PCM means...
But if I get the jist what you are telling me, it seems like if I install the lamps, I will be able to turn off or on the green indicator light...
Any suggestions on where to get replacement fog lights?
