I’ve designed a wireless turning and breaking light that can fit your helmet, rack, vest, etc. If you are interested on the circuit just mail me.

Can you please send me the circuit. Thanks Brian

MR16’s are a little big for this - I doubt you would want anything more than a 5/10 watt halogen mounted on your head (due to the heat). I would go with an MR11 bulb which is smaller (also available with led’s - you could use a much smaller battery to power it as you need 12v but not the same ampage).

On my bike I run a 13.2 volt lithium ion battery with two 20 watt MR11’s mounted in VistaLight bodies for over summer as they hardly get used (which do get very hot - must have burnt the kids hand who tried to steal one a while back as I found it on the floor next to my bike - that’ll teach them for trying the lights before trying to steal them).

Over winter I go for two MR16’s.

I built a very similar MR16 lighting system (although frame mounted)and was able to use a NiMH battery pack to get a little higher charge/weight ratio. Although I spent more on the battery pack, I saved money by using an RC car battery charger that I already owned. The charger was for a 9.6V battery pack and was rated at 12V, 300ma. I had the battery pack made by Batteries Plus, then used the RC connectors just like you did. It was a 12V pack consisting of 10 AA sized cells rated at 1.2V and 1800mAh. I’ve been getting a consistent hour out of the system with a 20W MR16 bulb (as would make sense since Tim is getting ~2 hours out of a battery with twice the capacity. I hope to have a description of it up soon on NickSuch.net. Thanks for sharing your helmet mount instructions. It will be a big help, as I move from road commuting to night trail riding.

Nice mod however the battery looks a little heavy, if you don’t need the light to see (I mainly use my bike light so that cars can see me!), I suggest using LEDs as they are very bright but don’t require a huge battery. I mounted 5 LEDs on my helmet with a 9V battery and a simple flashing circuit and can’t tell the difference in weight!

I have made similar lights and housed them in 40mm upvc plumbing fittings - they fit pretty well after a bit of whittling!
