Headlight not working…

Quickbrit · Nov 13, 2022

My headlamp and tail lamp are not working (the brake light does though) - I’ve replaced the six relays that I could find (two under the tank, and four in the tail). I’ve checked all fuses and I can’t seem to find the issue,
Am I missing a relay or can anyone else recommend anything?

TIA

Did you check the bulbs themselves and the switch?

Handle bar switch LHS, off-dip-main should sort you. Hopefully

Mine’s a 2015. I took the LH switch apart and I can’t see any issues. ..

Some suggestions:

Did you check the fuses with a meter? They can look ok but have a fracture in the conductor.
Does the headlight flash button do anything?
Try swapping the relays around.
Check the rear of the fusebox and relay sockets as the connectors have been known to push out of the back when not latched in properly.
Look for any broken off wires in those areas as well.

Hope that helps.

A bit of a long shot but relays polarised with diodes may not work as a direct replacement. Check power on the connector to the relay coil. A 12v bulb with a couple of wires soldered makes it easy.

Thanks for your help guys - I think I’m going to enlist a tech to come to my home.
