Dome Lights Not Working

[c33matt]

So I've had an issue with the cabin/dome lights in my C33 Laurel. They were replaced with LEDs before I bought the car, but they will not turn on. The fuse is good, but it looks like there isn't any power at the switch. Is there a common point of failure for the lights/wiring? I'd like to avoid tearing out all of the wiring unless I have to.

LEDs need to be installed  with the correct polarity . Spin them around and see if that works.

I took the unit out for the front lights, they work perfectly when connected to a power supply and there is no voltage on the harness that plugs them into the car

Do you know how to test for continuity?  If so, starting looking for for where the circuit is broken.  The pixies can't jump over very big gaps in the wiring.

Why not try to consult an auto electrical services. Anyway, have you tried to check the connectivity directly to the battery or you may use tester device by checking it connection from end to end.
