Are OE LED taillights a sealed unit?

Are OE LED taillights a sealed unit?
 
My apologies in advance. I know this is in the wrong forum. Just posting here to hopefully get a quicker answer.

I have an inch of water in my drivers side LED taillight. I'm surprised the unit is still working at all. I removed the taillight assembly and then the five screws I thought was holding the unit together but it still won't come apart. Just need to know if it's a sealed unit. Would rather not buy a new one as the dealer wants $256.08 and it'll take about 4 business days to come in.

yea it's sealed, but if water got in somehow, just look for that spot and try to dry as much as you can and seal it

Yes, it's sealed. A little heat, not too much (don't wanna melt it) and a very sharp razor blade. Work your way around the edge where the plastic housing meets and you'll find a spot where it will slide right in. Once you find that spot, the rest should come off very easily. Use a clamp and clear weather-proof RTV sealant to reseal it. You can get auto-marine sealant at Lowes that will do the job. You don't need a lot of it, just enough to seal the tail light back to the housing.

Be careful taking off the cover, it is possible to crack it. The sealant that they use is extremely strong. If you feel a lot of resistance, find another spot.

I turned the unit upside down (lens side up) and most of the water drained out thru the screw holes. I'm going to leave it off in the hope that by sitting it on a heater vent, the dry warm air will dry out the rest of the moisture before putting it back on the car. If that doesn't work, I read on another thread about heating it up in the oven to about 180F to dry it out.

i was going to say just turn it so where ever the water came in it'll drain out.

you can always put this in a bag of dried rice, that's an old electronics trick to remove moisture from electronics. ofcourse you want to make sure you don't have any access points that the rice could get inside the sealed lense housing.

It's in the oven now cooking @ 170F for three hours. I'll post results when I'm done.

Wow, this worked like a charm! I started at 170F in the oven and that wasn't doing anything so I increased the temp to 180F and two hours later, it was all dry inside. I was a little miffed at how much silicone it took to seal it up. The first application just drained right down the gap. So after an hour to let it set up, I added one drop at a time an hour apart to build it up and now it's all sealed up. :thumbup:
