Hey all,
Here's my creation with some pics so far.

My plan of attack on creating the lights was to first create a viable halogen system with cheap parts, then gradually phase in higher-end bulbs and parts such as LED based MR-11s and some Luxeon 3 and 5-watt bulbs (that i probably will build myself). And here is the halogen system so far...

So right now, it's a 20-watt MR11-based system running of a NiMH 12-cell array of 2250mAh AA batteries. I was considering buying a 10-cell C-size array from a vendor and fitting it into the system also. The batteries and charger on Ebay would be $36 or so.. maybe later...
so it's over volted right now.. but may scale it down to 10 units.
I also have another converted water bottle that houses my 3Ah SLA battery..

I'm not sure if I'm going to continue to use the 12- AA cells cause it's a pain to pull them all out and recharge. and I don't want to pay $40 for a 12/14.4V niMH smart charger and charge the batteries in the water bottle.. maybe later when I feel like spending money again.

All the parts were either Home Depot, Radio shack or a local electronics store.. The cord I'm using was on a wicked sale at Radio shack.. it is used as extension cord for their DC adapters. so I bought a couple of lengths and can string them together to any length if needed.

What's next: a good way to mount the system on handlebars, and create a second bulb housing and use lower wattage bulbs for high-low beam..

Total cost: around $40
