wowow amazing!!
Thanks for the specific instructions, I'm definitely gonna try one.
First I need to surf fleabay to find SA light with a switch ho!

stick the photos here when you are finished I'm looking forward to it:-)

pretty easy really

only thing is you need to get a SA light with a switch - I think a lot didn't have them, the switch is three way so I think it was for the old battery pack sets where you could switch between the dynamo and batteries

so

(note little black switch)

+

snap connector - 99p in maplins

+

AA battery box - also 99p in maplins - fits easily in the back of the light

then just chop the wire (SA lights had two wires, unlike a lot which had one wire as neutral was fed through the frame), connect the wires from the snap on connector (I'll solder this but you could bodge with some scissors and sellotape tbh) to the end of the wires and replace the bulb with the LED one

the LED replacement bulb has regulation electronics in and takes a wide range of voltages so you don't need to to worry about blowing it

you could just use a 9v battery instead of the battery pack too, don't know which would last longer though

the other good thing about SA lights is they have a hinged front for bulb replacement, so to change the batteries I will just need to open the front and disconnect the snap connector

simples

I'm thinking about making it trickier for myself and using all three points of the switch though, so that one on position is full and one is wired through a resistor for low beam =)

need to finish restoring the chrome first though, I got the front and back for 99p from fleabay but they were badly pitted and it's taken a lot of WD40, coke and brasso so far...
