Advice on replacing a High-Level Brake light, please.

[Revolvor]

The High-Level brake light on my Autotrail MH has stopped working. I am getting a "Bulb failure" warning light on the dash.

I believe I have identified a suitable replacement - a Hella lamp unit which comes with a 200mm bare-end cable.

When I unscrewed the faulty unit, I found that the cable comes through a hole in the rear panel, but there is only about 30mm of free cable visible. I had hoped there would be a plug/socket or at least enough cable to pull through, to remove the unit for testing before buying a replacement. If I'm careful, I should be able to cut the cable and solder on the new cables, but wonder where else I can fault-find the wiring.

Is it common for the complete unit (12x LEDs) to fail, or is a wiring fault more likely?

Edit: I had searched for previous similar posts, but didn't see this one. It still doesn't answer my question though.

High level brake light

I have an Elddis Evolution 196. The high level brake light does not work. There is no live feed when brake pedal is pressed. All other brake lights are working. Does anyone know if there is a separate fues for the high level. The wires to the light are very very short and have no idea where they...

I’d get it off first and have a look, it’s quite possible that water may have got behind it and a little corroded connection is affected and with a clean up may work again…

hard too say , to determine, you will need to check with a multimeter if there is 12v at the light

The problem is that it doesn't seem to come apart, and there is just 30mm of exposed cable that goes into the back of the unit. I will have to remove the outer sheath and then expose the +ve and -ve wires Difficult, but not impossible .... apart from working on top of a step-ladder!

Poke a couple of pins/needles through to the wire to test for 12v supply.

I'd have thought it unlikely that all the LEDs have failed. I have one dead bulb in my high level lamp but cannot get any further as I can't get the flaming thing out. It's still legal with just one out so I've let sleeping dogs lie.
