Rated 2 out of 5 by JeffR from Time waster due to low quality wires Installation of these is great until you have to wire them in. The wires used on these is the standard two wire with one having a red stripe. The problem comes when pulling the two wire apart to strip them and connect to a power supply. The wires are so difficult to pull apart that the insulation is pulled completely off the wires that you will spend much of your time covering the bare wires or using a knife to cut exactly between them, which doesn't always happen. Do to this I can't recommend these until they replace the poor quality wire
