I bought this LED kit for $13.99, it had enough modules to do the interior and the bed. I'm very impressed with the quality for the cost of these modules.
The modules are UL listed, waterproof and pre-wired. The kit came with a harness, additional wire, real 3M adhesive pads, and screws if you chose to hard mount the modules.
The light is 5000k, and looks to me just slightly yellow to the factory interior lights although that might just be the surface its shining on, its very close.
I used 1 module at each seat and put the remaining 8 modules in the bed in addition to the factory bed lights. The bed has areas under the rail where the steel is stamped at an angle that made a perfect spot to mount these lights.
