Lights - then and now.

Has anyone experience of fitting 6-volt LED headlamp bulbs to the original reflectors of an early Ruby? The original bulbs might be described as having a "3-bayonet flange".
At least we don't have to cope with this, fun though it might have been:

Back to the originl picture.

Whatever is coming th other way presumably has an arc lamp.
I used to travel 60 miles to my parents home most wekends. There was a gently curved part of the main road with an extensive  flat unsealed adjacent area. it was very difficult to find the edge. Straying into metal at 45-50 in an RP is not recommended.



If any car had a fitting like that today it would promptly be stolen.

That’s a typical Norfolk cyclist — middle of the road, no lights and not a care in the world

That's an APF (American Pre-Focus)  bulb and certainly not an original fitment.
 I first came across these when they were sold by Dave Phillips of the The Seven Workshop in their excellent replacement reflectors.
I have bought 6v LED APF bulbs from Peter at Classic Regulator and Dynamo Conversions of Lincoln, one of the cherished suppliers.

Thanks for the information, Stuart. Purchased from the recommended supplier, fitted - and they do seem to be a great improvement.
