Yes mate , tried to trim on headlamps , rear gear everything but nothing no show even life in wire, all fuses are fine .

Change the bulb?

MD & GERBIL

That’s new led light smd , there is no life there in wire . Can someone know where wires are connected mainly

If the feed to the light on the light has no power, then we can ignore the bulb/LED etc.

So which fuse is the rear light fitting on?
If that is live on both sides when switched on, then there must be a break in the wire.
If not live at the fuse you need to go back to the switches. If they make/break correctly then the wiring between there and the fuses is broken.
Same applies to any relays fitted.


You need a wiring diagram and meter (or bulb and wire) at the least. And need to systematically see where there is and isn’t power and narrow it down to one component/ section of wiring.

I can’t see any short cuts. Check each component and section of wire.
