Hello, i have 2 laser diffusers that are the thin long narrow type there are 3 wires in the wire wrap, a yellow, a red and a black, i want to know if i can just hook these up to 12volt power and have them run with no led's and what wires get hooked up to where, im a novice, but assume red power, black ground, and yellow was to the LED? ? i have 2 and will mount them both up front, on either side of the license plate, i assume that is best or please advise.. and also do they both get wires seperately to the power source or can i connect the two and then run one wire to the power and ground? are these still effective? thank you room !!!!
