Brake lights work no taillights

Just pulling out from a great weekend of camping in NC. It's raining 😢
we notice our trailer lights arnt on.
The brake lights work and signal lights. Don't see an exterior trailer fuse in the box.
At least we r traveling in the day time😳
Any suggestions? Driving a F250
Did I mention it's 46 degrees and raining? #goodgrief

What year is the F250?


I suspect that you have a blown fuse Check in your owners manual and look for the Trailer Running Lamp relay or something that may be worded similar depending on the year the F250 is there should be a fuse associated with that relay

Do you have a Volt/Ohm meter? If not head over to Wallmart and pick one up. One of the best tools you can have.

There are 2 ways to look at this.. from the TV end or from the TT end. Lets start from the easy end the TV (F150 side). Start the engine, turn on the running lights and take the volt/ohm meter set to DC VOLTS. Put the Black lead into the ground connector of the plug and the RED lead into the "Markers" lights (running lights) connector. You should see 12 - 14VDC. If you do, the voltage is leaving the F150 ok. See below picture for pin-outs.

If you have 12VDC at the TV's connector let us know and I will go over the TT tests you need to do.

So you have no running lights but have brake lights? Does the truck have lights?

its a 2015 250 and we think you are right Gonna relook when we get back home. That fuse box is not in an easy position to get to on a cold rainy day. Glad we are traveling in day light. Thanks for your help!

In the future, as an expedient, you can jumper between the top two pins of the 7 pin connector and power the running lights directly from the battery/charging circuit.

The trailer light fuses on my F350 are in a box under the hood.

It's in the trailer then. Or it's a bad relay in the Smart Junction Box under the hood.
