Hello all , recently purchased a 1957 D3 , runs like a top but none of the lights work on it , In my research I’ve read that there was a battery in the headlamp on these , does anyone know if you can still get them , and if not is there a way to rig up some sort of bypass to get lighting on it ?

 

Thanks for any and all help

Joseph

Hello Joseph and welcome to the Forum. The battery in the headlamp will do absolutely nothing for your lights at all. They are still available - at a cost! but are virtually useless. I can't think of a single owner who bothers with one. You need to have a good look through the millions of lighting/electrical topics that we have here. Try "D3 lighting/wiring bantam forum" for starters in Google. If you do a wee intro in the Introduce yourself section and tell us a bit about yourself and your bike(s) that will help greatly as none of us know what spec you are running.

All the best,

Stewart

Thank you for the welcome Stewart . I’m excited to be able to access the forum and have added some info about myself and my fleet. I live in rural upstate New York and have started my cycle collection about ten years ago. I just added my D3 bantam to the fleet this fall and I’m working on my knowledge base of these bikes. I have really enjoyed the little bit of riding on my D3 so far but I need to get my lights working as spring is now soon to begin! I’ll begin searching the forum for me info

Thankyou

Joseph

Don't restrict yourself to the D3 when looking for info, you will find that apart from some minor details, electrical systems were similar on the D1 - D7 models. I have a '56 D3 if you need any reference info.

First of all is it a battery lighting version, that is, does it have a battery with it? My 1955 D3 was a battery version so there was no battery or holder for it in the headlamp shell. Which as I understand it is so the AC lighting only versions can have park lights. But as been said, don't go there!
