Tail light help

[Slime]

I am going to search around and see if I can find any related posts. Also thought I would throw out a new post to see if I got any good advice. Heading out in our new-to-us travel trailer and found that the tail lights don't work. The flashers work fine and the brake lights work fine. Just the tail lights when I turn the headlights on. All of the lights around the top of the camper come on when I turn on the headlights, just the two taillights don't work. Tried swapping out a bulb but no change. We aren't driving at night this time so no big deal for today. Next weekend we may not make our destination before nightfall so I need to figure this out by this time next week. Thanks for any suggestions.

It is a 2007 Jayco JayFlight 31BHS. Tow vehicle is a 2001 excursion.

Thanks.

Sounds like it could be a wire in your pigtail plug, or the receptacle in your tow vehicle . Oops I take that back, you said marker lights work so loose connection after the the plug somewhere!

Try taking off the lens on one of the taillights and check for voltage using a volt-ohm meter. while there see if the wire may have slipped out of the wedge connector (bare wire is slid into a wedge shaped slot.) Also check if there is slop in the bulb holder if voltage is present. Hope this helps. Joe

If such a thing even exists, is it possible that you have a flasher-only bulb in the sockets?
I understand that the bulb should have two filaments...

Thanks for the advice on this. It was a loose connection where the wires connect to the bulb socket (happened on both sides). I tried to tighten them up but I think I will have to keep an eye on them.
