wired up a vincent tailight (has 2 single filament bulbs, one for tail, one for stop) to the enfield. it's six volt so i put 2 single filament 6v bulbs in (shop gave me 6v/8w ones). won't light up.
I've put my wire tester on the bulb contacts, and it lights up, so there's power to the contacts in the light housing. but the bulbs wont light up. it had a dual filament lucas type light before this.
I haven't had any trouble using 2 single filament lights in place of a dual filament before, usually plug n play, so has me puzzled.
and yes the light housing is bolted up tight so Im assuming it's earthing okay?
any ideas? have pm'd Scotty so hopin to get some advice from the expert, but thought I'd chuck it on here anyways, in case some smart cookie has an idea
