Hi
I have a Volvo fh13 o7 plate,
The back lights on the lorry are not working,
Or indicators but they work on the front,and when I have a trailer behind none are them are working either ,
Does anyone know which fuse this could be ??
As on the panels it doesn’t say rear lights or anything obvious
Thanks
Sounds like earth connection has been cut somewhere if none of the rear lights are working, workshop job to check or call breakdown as it’s not driveable like that.
Rear side lights left/right are normally on different circuits.
No trailer lights either, it is much more than a fuse.
As @martin says possibly a physical cable break, or maybe summat computer related.
