Sturmey Archer Dynohub lighting set LED conversion

No doubt this topic has been covered umpteen times, yet a search reveals nothing.

What I need is a numpty's step by step tutorial, without all the electrickery gobledegook.
A guiding hand required, please.

The best place for that is the Dawes Kingpin FB group there’s a guy there called Melo, has done the conversion many many many times.

The simple options are to either replace your lights with LED versions, or to replace the bulbs in your existing lights with LED replacements.
In terms of beam pattern, replacement lights will almost certainly be an improvement, replacement bulbs may not be.
Either way, you'll get more light, and no blown or dimming bulbs

Classic33, thanks.
I googled the FB group and had a trawl until I was asked to sign in...end of.
I appreciate you trying to help.

I used Reflectalite parts to upgrade the dynohub lights on my Rudge. It's really just plug and play and the eBay description explains what you need. The only problem might be some Sturmey lambs took a capless push-in bulb and if you have those lights, you'd need to swap them for lights with srew-in bulbs.

This conversion made an enormous difference to the usefulness of the lights. With the original bulbs, they're really just to be seen with lights. Now you could ride unlit roads. There's a strobing effect at low speed unfortunately, but that is the nature of the SA dynohub.

If you're not worried about originality, the SA hub will run something like a Basta Pico 30.

You might need a voltage regulator for the Reflectalite bulbs. They protect themselves above 6V but become quite dim when they do so. The voltage regulator is a zener diode and a big resistor between live and earth. It gets quite warm, showing how much power is wasted when driving just a 1W LED.

You do need a regulator and Reflectalite supply it too. Just fits in the wiring between the hub terminal and the rest of the wiring
