I got tired of the awful Walmart switch box I used to control the lights on my truck cap. Damn wires kept pulling loose and switches sometimes would fail. Not good when your trying to turn lights on in the dark. Based on the reviews and nice big switches it had on it, this is the unit I got for controlling the lights on the truck cap.

The great thing about this unit is it uses blade clips and you can freely re-wire each part of the unit as you choose, to disable lights on the buttons or for that matter switch off the voltage meter, so it's not glowing while your trying to sleep.
