I kept going through them until I polished off the corrosion on the bulb sockets off. Water getting in, or a short in a wire could do it as well. I was quite surprised to find that the corrosion could cause it though.

tail light issue....

Yes, I've been having the same issue since I've had my 88 turbo for 7 yrs now. For me, it's the rear passenger tail light, water leaks in through the seals and there's condensation. I open up the back of the tail light and there is a lot of corrosion and bulbs are usually burned out.

I was told this was a common problem with Supras, and to add some black silicone to the outside seals of the tail light to prevent water from getting in. I have not done this yet since I pretty much gave up in trying to get that tail light sensor to turn off on my dash.

I made several replacements with several bulbs, and they always seem to be working when I put them in, but for some reason the damn sensor light comes on when I brake. I check the bulbs, they seem to work. I got fed up and just let it be, so that light sensor is part of my everyday drive.

If you have any inputs or remedies, I'm open for suggestions.

Thanks,
EB

^ SIMPLE, Order & install NEW taillight gaskets. $14 each side ordered from the below site. The sponge rubber that they are made from dries out with time allowing water to leak thru.

Hey Mike,

Thanks for the tips and the links, I should have looked into this years ago! I'll give it a shot.
