Ho, ho, ho Leon. I didn't say Villiers lighting was good electric lighting, just that it was there. It was much the same as old fashioned bicycle lighting with the dynamo you ran off the wheel. Maximum available wattage in early sets was 4.5 watts for each lamp, tail and head. Still, a light you could switch on without stopping was much better than the acetylene option. Stop, turn on water, wait, when you can smell gas, light a match!
Of course you are well aware of the Sunbeam/Villiers connection. Both were owned and started by the Marston family so were very close. Dad first made Sunbeam bicycles then motorcycles. Sent son to the US to look at mass production methods . Son returned with US machinery for making bicycle parts which he set up in Villiers St. Son ended up making two-stroke engines as well as bicycle parts. If it hadn't been for the Sunbeam factory needing to increase production to fill bicycle orders Villiers might never have come in to being.
