Hi, I'm an old newby. I switched on my headlights Wednesday night, they went straight off again, I live in the country so no streetlights. I have replaced both bulbs, both fuses, R9 relay, indicator/dip switch, took the main light switch off am baffled by a bulb(?) similar in size to instrument light bulb which fits into back of main switch housing, I put a bulb that fitted(3watt) which lights when ignition is switched on, but doesn't show when installed into switch housing. Original was black so assumed blown, filament looks much stronger than bulb I installed.Can't find it on wiring diagram in Haynes, I still have no dipped headlights. Anyone any ideas why my lights still don't work please?
