I'm about to purchase a new folding bike which I will be riding a lot after dark. Being an electronics geek, I'd like to make some kind of led contraption to make the bike more visible and stylish at night (I already have a good headlight system).

I'm still working out the details, but I would need a handlebar mounted switch to turn the lights on and off. After looking around on ebay, I saw some motorcycle switches that looked cool. Does anyone know if these would these fit standard bicycle handlebars?

(also, feel free to link any cool led mods I could use as reference.)

Thanks.

Yeah - the motorcycle bar size is the same as hybrid, bmx or mtb bars.

I have an Old Night rider 12v double halogen light , they had a 4 position switch A,B,A+B and off,

Option Continued, remote button to sit near the grip.
mine has a lever switch directly on it.

Hi gentlemens,
I made switches for my bikes and it is very nice thing when you have at least two modes of lighting (strong and strongest) so that you can signalize to people on the way which are turn to you by the back to move away.

I also make mine, packing a bit more functionality per space. Yours look good, and seem well thought through. The only negative is that you need to take e-thing off to thread them on. I use hose compression straps. Incidentally, my last batch of the compression straps was purchased in a hardware store in Zadar , following the principle of never missing an opportunity of hardware-store sightseeing.

Nice Zadar, i agree with your principle.
Sorry didn't understand what you mean by e-thing off to threat them on?

I missed at first the crummier 2nd design in the last photo. I meant that to mount (should have been thread) the 1st design, in the first 3 photos, you need to take off the handlebar, shifter and brake lever, which is inconvenient. Incidentally, where the heck is your lever for the rear brake??

A well yea its a kind of complicated with mounting.
That bike doesn't have rear brake hand lever, have torpedo rear hub.
But it doesn't have a chain as well...
Thats my cardan geared customized city bike .

Have you got an access to some serious machining tools and appropriate skills? It certainly appears as if custom elements were for you like bread and butter.

I just did the same project and used this switch.

I have a small solar cell and battery on my bike rack. then I have it powering an LED headlight and tail light.
So much easier flicking this switch instead of multiple things all over the bike.
Just make sure everything is the same voltage, I chose 3V since bike lights usually run 3V.
12V would open up lots of car/motorcycle options.

I also added EL wire front and back but they come with an inverter/control box so they have to be switched on after the main switch.
I could probably rig the box to always be on and controlled by my bar switch, but haven't bothered to figure out the pcb board yet.
