Has anyone used the single LED's made by Nitro? They each have their own resistor and can be wired together. I am using 11 of them, they are rated for 6-16v DC. I am using a switch and wiring the directly to the battery but here is the deal, I need to get 12v or so to each of them, I want to run them in series to avoid the use of an extra wire when running parallel. The way I figure it, I am going to need a dc-dc step up transformer to do it. I need to produce 110-130v dc to run the series. Anyone got any ideas?
