I wired a basic set of lights - including the under slung side light up front. I wired a head lamp for main and dip and a tail light- I also wired a separate brake light at the back(reason to be explained).
I had got an original 1950 head lamp unit- which has the small underslung side light (same as a daimler dart wing light) - the things we find out when building old bikes!.
The reflector was poor - so I cleaned it up as far as possible - still crap.
The glass head light lens is not really a lens and does not have any serious focus.
So I had a damaged head light from and old moto guzzi, which had a modern H4 bulb holder- I cut the guzzi reflector and glued it onto the back of the BSA reflector, just enoguht to create a H4 bulb holder (the glue is silicon based and is removeable)
I then got a reproduction tail light as per the old M20 type- the one that arrived initially was particularly poor quality and after an attempt to do something with it, to make it presentable- I threw it there and ordered a differnt supplier's version - it arrived and was excellent quality.
I now had to make a rear number plate holder and light bracket- I did this out of aluminium plate for the number plate and some light stanless steel for the bracket and retaining strap.
It took me 4 hours to make a brake light switch bracket - so that it would be adjustable if I moved the wheel for chain adjustment.
After wiring the bike I fitted LEDs to all fittings - main head light, underslung side light, tail light and I got a 'rubbolite' truck LED fitting for a brake light - see photo
