I bought a reel of led's, and they can be cut every 3 led's, so I used 2 strips of 9 white led's, and 1 strip of 9 red led's. This was just a guess and time will tell if I've used too many or not enough. You also need to junk the circuit board from the unit. If I didn't have enough wire like yours, I would cut one wire, extend it, then cut the other one and extend that one, so you don't lose the short wires into the ceiling, but I'm guessing you probably knew that. Led's rule.
