LED park lights

[MyHappyPlace]

I have a 2017 Thor Challenger 37LX. How are the front LED PAR LIGHTS controlled? I can’t get them to turn on. I can run 12 volts directly to them and both sides light, so the work. But, what switch should control them?

All park and cleance lights should turn on with the headlight switch. Look for a loose ground for that string.

All the lights work, it’s just the LED strip of lights under headlights.

My understanding is that LEDs are polarity specific. Is it possible those lights are connected 'backwards'? If you can trace to where they connect to the RV's lighting circuit, see if the pos & neg connections are or can be reversed.

I wouldn't waste a moment looking for how the should work.
With these(or similar) almost no wiring needs done.

Break out the multimeter and start wire tracing. They should light with the rest of them.

I am not positive, but are they just daytime running lights? Do they work when the engine is on the the headlights are off? I think that is what happens on our Aria.

I had the same issue with my 2017 ACE. I ended up wiring them with a 12v relay to a hot wire when the ignition switch is on. Work fine now.
