Hello ladies and gents. I found where someone had asked a similar question to mine but had not included enough info so didnt get a good answer so I am going to give it a shot. I would like to build some accent lighting for my motorcycle using some super bright ultraviolet leds. There are several companys offering pre made products and controllers but they are super proud of there products. I am looking for a little guidance in selection of the leds and what my circuit needs too look like, also...how I should mount them. My first thought is to use a bread board for the array, solder the leds in parralell and use a resistor to get the voltage on the array correct for the led.Then just stick the bread board where I want it with some double sided tape. Asthetics dont really matter as you wont be able to see the fixture itself...only the glow. I have done some small electrical assembly but it has always been from a print....no experience designing my own circuit. I am also wondering how I could build an led array on a flexible strip. Some of these companys are offering led"stips" that are flexible....like a ribbon cable. Any guidance or advice that someone can give this noob?

Running a set of LEDs isn't terribly complicated, not much needed besides an appropriate power connection and maybe a switch... The real difficulty in your situation is making it robust and weatherproof. And making it not look like a giant plastic wart on your bike. Possibly some clear tubing sealed with silicone at the ends, or something.

I would probably use LEDs in series, until the voltage drop is near your supply voltage (I assume 12v) and maybe have a smaller resistor to take up the slack. Otherwise I believe you'd be wasting more power on the resistor than the lights. If you need/want more LEDs, make a duplicate string (until you're happy) and have each string in parallel.

I'm sure there's better ways to do it, but I'll let somebody else figure that out.
