Like the title says how do I remove the fog lights from a 99 sc300??

If I remember correctly, it two screws on the side and one screw on top.

Three bolts, that's it. I believe they are 8mm. Make sure to unplug the wire harness before yanking them out. I believe you have to unscrew the fender liner and remove the engine undercover to access the lights. It will probably take 30 minutes per side.

Using it for the supra?

Naw just got sum yellow fogs

I was able to get mine out by sticking my entire arm into the hole in the bumper next to each fog light and using a mini philips screwdriver, but you need small hands.

Took about 10 minutes per side, 8 of which were finding the screws.
