Nilight TR-05 LED Truck Bed Light Strip Kit, 2 Strips, 60 in, 180 LEDs

Two 60 inch light strips that stick under the rails of your truck bed so you can see what you are doing after dark. The kit comes with the on/off switch, a blade fuse, and a splitter so both strips run off one wire. Universal fit, meaning it is not cut for one truck, it works in any bed.

why this one — Cheapest thing on this list that solves a real problem. A lot of bed light kits leave out the switch or the fuse and you end up buying parts twice. This one has both.
