Trailer lights
Hi.
I’ve plugged in my Ifor Williams trailer and none of the lights are working. They’re LED but have been working for the past couple months. I’ve checked the fuses and there all okay aswell. My question is does anyone know what’s wrong with it and how to sort it?
Thanks in advance

LED's will work but there will be a can bus "blink" unless resistors are fitted. Likely failure is the plug from the trailer and usually the earth.yµ (idµ - eAµ) ψ=mψ

Yep LED's can cause various issues from pulsing to just not functioning at all, you need resistors for the indicator circuits and relays to stop the pulsing.

I would disconnect the trailer and check the voltage at the vehicle plug. Next I would take a 12v battery and check the trailer connections. That should give you a starting point.

check fuse link 27 10 amp, check voltage across earth and stop, tail blinkers often it is one of the supply lines touching the ground

Do you know that there is a fuse panel in the lefthand side at the rear?

You can get corrosion/water inside the female socket on the car, check this as well and spray with water repellant spray (WD40 or similar).I want to see the sweets before I get into your windowless van... I'm not stupid!
