I use some UV LED's in one of my tanks and can only see it with a camera or phone.

3V should drive the LED's fine, again you will not see any output since we can't see UV in that spectrum.
I'll try it again. I'll finish installing it and see if it lights up the BBs. I knew I wouldn't (or shouldn't) be able to the LED's output, but it should cause the security strip on a bill to flouresce...teeth, too, I think. Couldn't get any of that to happen.

Also, to view an IR LED, an easy way is to use your phone camera. Try to get a half dark area and point the IR LED at the camera and add power, it should glow on your phone screen.
I'm interested; but, I'm not sure that I know what you just said. What is a Ubec? Inline converter...is that a resister? Do you have a wiring diagram that would show where to solder these (positive side, negative side, etc)? How would this affect the overall circuit since I'm tying into the headlight circuit?
