Sealant for Tail Lights

Had a taillight out so I replaced the bulb. In doing so, it appeared the tail light had some sort of clear-ish sealant or glue applied to keep water out, presumably. Can someone direct me to a source of this glue-like substance so I can re-apply?


I have a Cherokee 294BH.

Thanks!!

If you are talking about a substance on the bulb itself, that is used to make a good seal and keep water out of the socket. It conducts electricity. It is readily available at any auto parts store. Available in little single use packets or larger tubes. It is silicone dielectric grease.

A correction: dielectric grease is an insulator; it does not conduct electricity and repels water. Common automotive and RV applications include bulb sockets, spark plugs, and trailer electrical connections (TV to trailer, as an example).

If you mean there was clear sealant/caulk around the tail light red lens I would
suggest clear silicone RTV. Get the small "roll up" tube rather than a big
caulking gun size as it's nearly impossible to store an opened tube more
than a very few weeks B4 it get's hard in the tube.
You don't need much for a tail light lens.

My tail lights get dirty inside from road grime. I've cleaned them twice!
I need to try and seal mine. They sure as heck aren't any where close
to being sealed the way they are made-- very cheap stuff!

Clear RTV silicone in small roll up tubes can be hard to find. You can get
the caulking gun sizes at almost any home center or hardware store.....
In fact, if you don't use a lot you could use white and you can get that
anywhere.

I apologize for my post not being more clear. It was a glue-ish sealant around the taillight cover, not on the bulb. The bulb was dry and clean and had no residue or such substance on it that I could see.

Thank you for the help. I'll investigate the RTV sealant.
