LED's are definitely polarity sensitive and are extremely sensitive to good grounding. Get a couple of pieces of wire and touch the lights directly to a battery. If no light, reverse the wires. Still no light means bad lights. Someone mentioned a relay, which you should have had for the original lights. You shouldn't need the relay for the LED lights (less power required) but that relay may be keeping the LED lights from working. You'll need to bypass it and power the LED's directly.

Fog light update:
I de-installed the lights and verified they worked directly on a battery. So a relay is not required. I also addressed the polarity question and the installed polarity/wiring was correct. I checked the power at the wires to the lights and nothing. So I'm in search of the fuse location. As noted previously, the fuse location is not noted in the owners manual so a call to the Forest River Tech Center will occur tomorrow.
Best regards,

More than likely the power location under the hood. I believe the A class chassis is like the C class Fords with a fuse panel under the dash and a power panel under the hood. Driver side and there should be fuses and relays. Could be a bad relay or fuse. To check relay, Ford uses same in most locations. You can swap them to see. Chassis manual or on line can tell you what is where.

Nothing like the Ford! Freightliner chassis. Berkshires are a beast of their own!

Sorry about that. I guess there is nothing in the front other than inside under dash. Any compartments near the front with wiring? I guess they can, but I cant see wiring everything to the rear.

Fred, did you check to be sure high beams weren't on as suggested by some previous posters?

No, our priority does seem to be the same, family first, as it should be. I apologize for being to quick to judge, I let words go to the keyboard that were better suited to keep to myself..
I know nothing of a Berkshire / freightliner so I will need to bow out of this conversation. I will offer one last thing to check or at least maybe was already thought about, did you test for power a bit in from the old ends of the wire? I say this in case water intrusion caused corrosion into the wiring a few mm or so and is not able to conduct power anymore. Otherwise I would guess a fuse shorted before a relay went but who knows, good luck. Electrical gremlins can be a bear sometimes.

You are aware there are four fuse boxes in the compartment under DS. The fourth is located on the front panel up a little higher than the three facing the door.

Hey "Campin Cajun" - I wasn't aware of that 4th fuse box! I pulled the cover just now and I'll look more closely tomorrow at early light! None of the fuse box diagrams in the owners manual looks at all like this box.
Thanks!
Fred

No problem Fred. I hope you find the fuse.

Fog Lights - question of the day
Also I have bought led Rv lights that the black wire is hot. White is ground.
Most regular lights are white or red is hot and black is ground.

Success! With Motodad's advisement, I went back out and checked my wiring and I had presumed that the white wire was my power source. I rewired the lights with the black wire hot (remembering the polarity of the fog lights) and they are now working! Thanks for all the inputs. I really appreciate the assistance!
