WRT to your question about sourcing the LED arrays, So far I'm planning to buy a bunch of superbright LED's from our equivalent of Radio Shack (RS Components) and build them straight onto suitably shaped veroboards. I want to drive the indicators through a low-wattage (or electronic) flasher unit using the existing cabling (they won't work the ordinary flasher relay because they don't pull enough current) while the taillight assembly should be a straight cut-to-fit part, replacing the current bulb holders.
The stock indicator bulbs, BTW, are 12v 10w IIRC - pretty dim affairs ... worse if you factor in a coating of road-crud.
If you connect identical LEDs in series (I wouldn't really do it any other way) you can light several LEDs with the same amount of current as just one on its own. You need to supply roughly 2V for each LED (actually about 1.8 - 1.9v) plus another 2V for am upstream resistor. So, 5 or 6 red LEDs in series need a supply voltage of around 12V + 2v for the resistor - meaning a bike supply of 13.xxxv when charging is fine. A resistor of about 220 Ohms for each series array should be about right.
Here's how it fits together.

The current draw for such an array would be somewhere around .015Amp ... I'd use 2 arrays arranged in a circle for a central rear light plus 2 more for two outer brakelights - the resistor for the lighting array could be slightly higher so the brakelight would appear comparitively brighter. All of this should fit comfortably inside the stock lamp assembly. It'll also leave spare juice capacity for a decently bright glow-worm up front ............. and some spare cash too. The cost of ready-made LED lamps is pretty breathtaking!
Note (blue and white LEDs take 4v and cost more - Red & Orange ones are cheap as chips)
