Water in Tailights

[93CB7Bruh]

My car has had water in the tailights since i've gotten it. I finally want to do something about it but not sure what causes water to leak into them . Any suggestions?

all the 92-93 CB7's that I've seen seem to have water in the taillights...guess it's a design flaw? You could try drilling a tiny hole or holes on the bottom of the housing to let the water drain out...or change 'em out for some aftermarket lights...

Don't drill holes in them

Open them up with a heat gun or the oven, let them dry, then reseal them with silicone. Then make sure all the bulbs are held in airtight.

Will drilling holes in the tail light affect it in some way? Not to long ago I realized my right one has a small hole drilled into it at the very bottom... it's been working fine and looks ok, but is there anything I should be worried about?

you could drill holes in them but it will only half a** fix the problem. It will let water drain but you will always have condensation problems. the best thing to do is follow fatboy1185's advice.

is there a DIY on how to do this. Cause my tailighs also have water in there. i have this problem for the past 6 yrs. they dry and when it rains i have it again.

dont ever drill holes in tha lights..cb7s are known for the frost in the tailights..just like leaking trunks..if its that much of a problem..get new lights n see if it was a bad set..not every cb7 has water in the lights..mine dont

[Highidlecb7]

most times the water gets in due to them not bein tight enough..causing cold air to make them frost up at night time..

Yeah, what fatboy said. My dad drilled his on a CB back in the day, nothing but condensation after a rainy day, or car wash...

window sealant ftw

open them up and reseal them with clear marine grade sealant, and fill the the holes that were drilled, if any.

When I blackhoused my headlights, I did it on a cool day (near freezing temps). When I siliconed my headlights together in the garage, they immediately fogged up after I sealed them.

I thought great, now I'm going to have to pull them apart and redo it. I installed them on the car anyways and within a week, all the condensation in the lenses had disappeared and has been gone ever since. You will also notice the headlights do have some vents in them too, thats what the black hose is on the back side.

So yeah, just take your tails apart and seal them up nice and tight. No more leaks. My 91 tails never seemed to have gotten water in them, but the right tail light that I got off a 93 has had some in at one point cuz the bottom and corner is all dirty inside.

I just recently fixed this problem.
I figured the problem was from a faulty gasket so I created a new one with this silicone putty thing. I thought I had fixed it until it rained. I opened my trunk and out comes the water. Water was getting in somehow and was routing into the light bulb casing (white cap-looking thing).
Thinking of where the water could possibly be going in from, I just silicone sealant and applied it all around the tail light whereever I saw a crevice.
Ever since this, water hasn't gotten in and I've driven through the rain.
Hope you try this and it helps.

All these suggestions are great I will get on it soon but right now i must fix an antifreeze leak somewhere, but that's another story

Not to mention mold can start building up to if it's not sealed properly. Moldy tail lights r not a pretty sight. .. lol

I think I'm having the same problem. Nothing a little DIY cant fix.
