Okay my dad asked me to make him a flash light thingy, imatating This . he just wants the LED part to illuminate the blood trail, not the big xenon bulb. theres more out there like it, this is just the first i found with google. Now do you guys think those are just UV LEDS, with some red ones too ? i dont realy know if this will work, or how it works and just wanted your guys ideas. if you think it will work, im prolly gona mod it into a big Mag light.
