Villiers headlamp switch

[33d6]

I understand your lack of concern over lighting. Who does expect to go riding one of these beastliest at night anyway BUT, (there’s always a but) you do occasionally get caught out. Country town rides and rallies have caught me out a few times, somehow you end up at a local riders home or a different pub and bingo, it’s got dark quicker than you expected. I also like to have a brake/stop light fitted. I have little faith in the road users    following behind. Many only react to brake lights and never think beyond them.
You can fit a battery powered total loss system but then you’re always faffing around charging up batteries. Fit a basic direct lighting set up and you always have no hassle lighting but the brake light set up is iffy. There’s never an easy and simple 100% satisfactory solution is there.

I smiled at the 4.5v battery chatter. They can be sheer frustration. I don’t know exactly when they went off the market and I have mucked around making them up from two ‘D’ cells but eventually I got fed up and stopped bothering. I don’t know how many hours light they originally gave but wangling a replacement in and out of that headlight clip every month or so would drive me nuts.

I VERY much agree with this.
Almost entirely the reason for this exercise.
From previous experience, batteries can go for months without needing a recharge if this is their sole purpose in life.
With led varieties, the voltage can go even lower before they cease to show a brake light.

This thought had crossed my mind.
From the totally pristine battery carrier, I suspect the original battery was removed and never replaced. ?
I looked into these batteries, and they are still available.

Just powering it off the small 6v battery, with suitable bulb, would be simpler.
