No clearance lights - please help troubleshoot

[XLI]

My clearance / marker lights aren't working on my new-to-me 2006 Dutchman Kodiak 236 expandable. Brake lights and turn signals work. The 7-pin plug on my tow vehicle shows proper voltage so I think its something on the trailer. The junction box under the trailer appears fine and connections look good. Is there a fuse somewhere for the trailer lights? Thoughts on why they're not working? Thanks.

If you take a cover off a light, use a meter or test light to see if you have 12 v (+) at the socket. Use a jumper wire from a good ground source up to the light. It could be a bad ground, this test will show that if it is the case.

It would help us if you list details on your trailer, you can add it to your signature.

Wouldn't you know it, after needing with it, the lights are now working. Don't know why. Thanks anyway.
