Replacing taillights

It's probably not a "plug in". But you can splice in a plug in connector to both your existing wiring and your new tail lights and it will be easy to change them in the future.

I think the TT would have to be really old to not have socketed bulbs in the tail lights. Pull the lens, if the bulb comes out the base of the bulb should say what type is is... probably 1157 if dual element, 1156 for single. Once you know that you can lookup LED replacements.

If the bulb isn't removable (never seen one myself) then wiring in a complete replacement unit should work fine.

One thing to check, if your TT is really old it could be 6volt, could also be positive ground. You'll want to know that....

You can pull the old ones off, cut the wires and replace with the taillights you want. Splice the wires to the new unit and seal the edges to keep water out. Bingo you are ready to roll.

sounds good ill probobly just put a new led light in then was just wondering if the wiring was the same

Depends on what you are replacing.
If you are replacing JUST THE BULB, no problem in most cases.. However SOME LED lamps are kind of fussy as to HOT and Common (Ground) leads.. Some tail lights on trailers MIGHT be "odd" but I would expect this to be very very very rare.

(Dual element lamps like the 1157 MUST have the "Shell" grounded or they do not work properly)

ONly problem is making sure the new one is as large as or larger than the old one. so it does not show that you swapped them.

I did this just this year. Installed Bargman LED's. Took a couple of hours but was not hard. PM me if you want more info.

YOu still haven't said if these are dual element bulbs or not.

If they also serve as turn signals, putting in a high output, dual use LED (expensive) will probably result in the turn signals flashing too fast.......and they may not be any brighter at all viewing angles than your originals.

And if the brightness problem is due to a fogged lens, a brighter bulb won't really help that much.

I suggest that for about $2.50 per side you get new bulbs, clean out the reflector, lens and bulb socket and see if that helps.

P.S. Most tail lights really don't look that bright in the daylight.

If your trailer turn signals are simply wired in to your tow vehicle's turn signals, the "fast flash" likely won't be an issue since there will still be sufficient load on the turn signal circuit because of the tow vehicle's lights. If, on the other hand, the trailer turn signal circuit on the tow vehicle has it's own separate circuit/flasher, then the "fast flash" could be an issue, although it can easily be solved by wiring in a resistor to add load and fool the flasher unit.

Or changing the flasher...

While the trailer lights may be a separate circuit (and indeed not infrequently are), I would be very surprised if any vehicle uses a separate flasher for the trailer turn signals. That would mean that the trailer and tow vehicle flashes would not be in sync with each other, which at the least would be confusing to drivers following (who might quite reasonably think it to be two separate vehicles).
