You can try drilling a couple small drain holes on the underside of the taillight. It won't be perfect but it should help.

I imagine the water is intruding through the top where the lens and housing meets.
I’m sure some glue or silicone gasket maker would seal them right up.

every inch of the outside seams were siliconed.....now I know why my expensive auxito LEDs kept going bad ....I could drill drain holes.....but I still need to know how water is getting in
I could buy a used housing ....but I would have the same problem again

At that rate I’d fully separate them then reseal them. Water must be entering from the top if it’s unable to leak out the bottom.

did you prep the plastic before sealing them with silicone? You Need some auto body solvent before sealing them up.

If you trust him, IROC Motorsports sells brand new lights. Not cheap, but they look cool.

I would not trust IROC Motorsports. Various negative posts on here about them (and their other names).

There are new aftermarket Camaro tail lights on ebay for $45 - $290.

For Firebird, I only see used ones.
