Default leaking taillight

My right rear taillight fills up with water after a big rainstorm. It damaged my taillight harness from corrosion. Is this a common problem? I was thinking of putting some silicone or somethin on the seal. Cant be having a turned out signal.

Thats pretty odd... I have actually never heard of that problem with the SE tails

I still have that harness here if you need it

SE tails are still built like SSEis sort of...

But i bet you either have a crack somewhere or there is a hole around the edge somewhere of the two peaces.

If someone else doesn't ill go take a look at my old SE tails i have in storage when i get home from work tomorrow and let you know where the leak may be coming from.

Actually, the only thing similar about the SE and SSE tails is the base.

The lense and reflector are two seperate pieces in the SSE tails and the lens is clipped on to the base.

The lense and reflector on the SE tails are actually one piece that is melted to the base and can't be removed.

If there is a leak on a SE tail, there has to be either a crack or the light is broken where the lense and base are melted togather.

My SSE tails leaked because the tops delaminated very badly. I assumed that was the common failure mode. The SE tails aren't laminated, and can't delaminate.

I've never really studied SE tails though, so I can't say where the leak might be from.

As a temporary "fix" you could drill a small hole through the bottom of the tail, into the turn signal cavities as a drain. That would at least keep them from filling to the point of draining into your trunk. Might not be the best route if you plan to fix and reuse them though.

SSEi tails do not leak just that one way either, that can also leak at the seem where the outer lens and the back part meet.

and they do not leak just because they delaminate, they delaminate because of the leaking.

Check the bolts. I found both my rears were broken. I just got some good adhesive/sealant and bye bye leaks!


Again I misread the post. Your problem is water getting in the lens not the trunk!

Not sure about that. Mine seemed sealed up pretty tight except for the 1/8" gap at the top due to delaminaiton. I don't care to hi-jack the thread and turn it into a "chicken vs. egg" debate, but I'm not convinced. If water caused delamination, seems like the bottom (full of water on mine) would have delamniated too, and allowed the water to drain. Would have been nice, actually!

But that'* not to say that the seams never leak. That could well be the case here, since it'* an SE tail.

well lets start another thread for the SSEi tail water thing if we want to keep talking about that

But far as the SE tails, I will know when i get home today, im going to get mine out of storage and take a look at them and i will know in a second where it could be leaking from.
