Well I have an '88GT and I'm almost positive, you can't just replace the fog light bulb. I had one go out and thought I could just replace the bulb also but I think it's a sealed lens. I bought a new fog light assembly for the left side for $25.
If anyone can post pics to show how to replace the bulbs, I would love to see it.
I just did some research on this and found out that you CAN] replace just the bulb...but....getting the lens to come off is another thing without breaking the cheesy lens clip that holds it on. Installing a new foglight assembly will be MUCH easier than screwing around trying to get the lens cover off without breaking it.
ok guys thanks for the help. this forum is great. no theres no sealed lens, bulb went right in. also did the 92 n up starter conversion with help from this place too. keep on rippin them gears boys. have a good one...
