Headlamp 80 series

BayBreeze

I had a similar problem with my 80 series. It ended up being a crook tail/brake light connection and bulb. The circuit diagram shows that these 2 circuits are only very distantly and operationly connected, but cleaning up the tail/brake assembly and a new bulb and the front right headlamp worked perfectly again.Mine was showing similar symptoms - ok high beam and intermittent on low.

dont know much about electrics, but have had a similar problem with a globe in our c/van, got some fine sand paper and gave bottom of globe and the socket a light sand and all was ok.

You do mean the fuse under the bonnet dont you?
not the ones by your right knee

"It's not the fuse & it probably is not the bulb as it works OK when high beam is turned on."

Most headlights have a low beam filament and high beam filament, and quite common for the low beam filament to fail and the high beam filament remain operational.
