Reversing lights not working

easyonthegas

Whilst checking the caravan lights, all lights work except the reversing lights, and no faults showing on dash screen. Mercedes estate is fitted with dedicated wiring on 13 pin electrics. Contacted installer and they advised to remove one lamp - and this worked. Now replaced the 21W lamps with 10W ones so same electrical load, and both lights work as expected. If you have similar issues with these CAN bus systems, this fix may work for you
