Rear brake light switch
What style of brake light switch would have been originally fitted to a '54 G3/LS and where / how would it have been fitted?

Re: Rear brake light switch
Hi
I believe it would be one of these:
The rear wheel spacer should have a reduced portion to match the hole in the plate.

Re: Rear brake light switch
Thanks for the info and photograph. Now I know what I'm looking for.
Mick... You say the spacer should have a reduced portion to match the hole in the plate. As there is only one 'spacer' apart from the chain adjusting snail cam, I assume you're referring to the spacer with two flats on that slides in the rear fork slots. Does that spacer fit through the switch plate simply clamp it to the rear fork?
Raffles... I've looked in the '54 parts list and it gives part number 018720 for the switch and 018763 for the bracket. Neither of those parts are listed on the AMOC Spares web site. They do list a 'Universal' stop light switch and a 'Replica Wipac' stop light switch but there are no pictures. Is it the Wipac switch that I need? Can't find any switch bracket listed... Would you happen to know what number it's listed under?
Many thanks
John

Re: Rear brake light switch
Hi
Sorry - my response was based on a full width hub set up and hence misleading, however the Lucas catalogues on the archive seem to indicate the switch is the same and Lucas pt no 31383 - another supplier lists it:
http://www.classicbikeshop.co.uk/genuin ... witch.html
The bracket on mine is made from 1/8" steel plate and could be made easily if you have basic tooling, (happy to measure mine in situ if it will help) - I guess it would replace one of the washers on your set up.
Regards Mick

There's a drawing of it in Christian's archives:http: //archives.jampot.dk/technical/Do-it-yourself_parts/Stop_switch_bracket_and_speedo_bracket__sketch_by_Don_Madden.pdf

Re: Rear brake light switch
I think this will be one time you wont need a part number. just phone press 3 ask for Andy and I am sure he will send you the correct bits.

Re: Rear brake light switch
I decided to utilise the rear chain guard mounting. I swapped out the bolt for a longer length of stainless threaded rod, made up a spacer from a piece of 8mm I.D. stainless tube and secured it with a stainless dome nut. It may not be 'correct' but it'll do for me
