looks good man. sick scooter.

Great scoot Mexicano.The stand you made is brilliant.I would like to make something similar.Thanks for the inspiration.

Mexicano - Amazing upgrades.

In regards to the LED lights, I'm not sure how well this would work, but I know ther are some *REALLY* bright LED light fixtures for "trailer lights" that you can pickup at truckstops, and sometimes a little cheaper, at a truck shop. Most of the lights have dual-power lines going into them. (brake lights, signal lights, etc) You could cut the "light" out of the "sealed fixture" and then place it basically anywhere you want, and their fairly reasonably priced. I need to take the front off my F12 and see if I can do something like that for my lights, as I have an american model, and the lights are ALWAYS on, and I think I'm having battery issues, because of that. Another type of LED light, and this could be BRIGHT. (think questionable road legality).

You can get a 1watt Luxeon bulb HERE. They will emit about 120 lumes at 3.5volts. (meaning a single bulb, would be about 1/3rd a 20watt halogen bulb) I would string a pair of 3 to 4 of them on a circut board, to desired brightness. once you get it wired, I'd cover everything in hot glue. (except the bulbs) to protect form the elements as best as possible. If everything would work as planned, you could get 25% more light than the halogen bulb, with nearly 1/6th the power. But dont ask me about how to build that setup just yet, as I'm not going into the hard part in my head. (getting the voltage set right)
But for front facing lights, I would think that would be about as good as you can get.
EDIT: There's a thing called "LED Power Puck" that will get the voltage where you need it.

In regards of the front led lighting, I got this better option for my Son's bike, less hassle:

However in regards to difficulty, some crazy glue, hot glue, so soldering, some fine wire, and a small piece of circuit board from radio shack, and about 30 minutes of your time to build the board, and then I would just tear the bulb off your old bulb. (preferably a dead one) Connect the leads from the old bulb base to the the puck, hot glue it all together, and crazy glue it to the old bulb base. (if you can mange to get it small enough, another thing I'm not sure of) and optimally, try to find a way to "seal" the electronics/LEDs. And you would if I'm not mistaken, have something close to a HID light, but LED. I'm gonna leave it at that here, and see if I can come up with 100 or so $ to retrofit the lights on the front of my R12, if I do, I'll do a guide. (not promising anything, but I like bright headlights, and their not that great right now)

If You really want to fabricate your own Led head light, this is a good option, 700 lumens, 12 vcd:

Thinking more about the project, I was already going in that direction. Here's another 700lumens 12vdc

Take into consideration that this led wont have hi/lo beam, with the TerraLux TLE-300 you can turn into 3 different beams.
