These led cabinet lights are excellent. These led cabinet lights were installed in my kitchen, above and below the cabinets. The only problem I have with the connectors is their size. It is way too large! These are my suggestions for installation. 1. Do not be afraid to cut or resize the wire. You will need to align the positive and the negative wires. Also, make sure that you use soldering and shrink tubing to splice the 12v DC. This is a much simpler installation and requires only 1/8 inch holes to route wires. 2. These lights come with a touch switch dimmer, which is great. However, if you wish to control them with a master (wall-mounted) switch, the electric dimmer will not remember your brightness settings and will be turned off when the master switch turns on.
