Hi All
Moving away from the legality and MOT requirements……I’ve invested in a pair of these headlamps for the Special. This is fitted with early Chummy scuttle lamps which only have double contact ba15 holders. So the following would apply to factory cars as well. Simply fitting the new bulbs results in dip on the sidelight setting and main on the head setting with no provision for sidelights.
So this is my solution… small ba9 holders clipped into the reflector using Terry clips and a motorcycle handlebar dip switch. The Terry clips are pop riveted to the reflector so only two small holes are needed (one for the clip and one for the cable). There was a bit of extra wiring to get an extra feed to each lamp and to the switch. The switch was meant for 7/8” handlebars but with a longer (bent) screw it seems to fit OK.
Cheers
Howard
