I've had my fogs for 3 years. Got them off ebay and had a local shop install them. They are the JDM knockoffs wired so that I can have them on without my low beams being on.

I just noticed that they no longer come on. My aftermarket switch still lights up, but the fogs don't come on. I checked the fuse in the engine compartment and it looks fine. Any ideas? Would a bulb have blown after 3 years? If one bulb blows will it cut power to both fogs?

did you check if the relay clicks when you press the switch? or maybe it could be the bulbs! Hey anything is possible!

The relay right next to the engine compartment fuse box? How do I test if it "clicks"?

Do you have a multi meter? Try checking voltage on the load side of the relay with the switch on.

What he means is the relay box clicks when the fog circuit is closed. So locate the relay box, stay close to it, have someone turn your fogs on, and listen carefully for it to click. Just to better understand the click, listen to your low beams turn on while standing outside with the hood open... its a real loud click. The fog relay will sound similar but probably not as loud.

The DMM will still tell you more than the 'click test,' and its a good investment to get one and learn how to use it. Test for voltage after the relay box toward the fogs with the switch on.

With just a shallow glance, since the switch still lights up, I would guess that the relay box is what is bad.

Same thing happen to me, i found out that the pin under the fuse box was loose. Maybe you can try pushing the pin in and give it a try?

figured out what it was today. Went through the top of the front bumper and got the fogs out of the bumper to try some new bulbs. I reseated the old bulbs and magically they started working again! Instructions for the bulb changing process are on the web in a file called foglights.pdf. You can find it here: https://www.hondacuraworld.com/Merch.../foglights.pdf

Firefox doesn't like the security of that link, but it worked fine for me after I created the exception.
