Inside Bed Light Install questions

Seen people put tape light inside the bed so at night it lights up to see things. Once saw someone hook up 12v tape to the tail light but it was only a 1 foot section.

I was wondering how long of lengths someone can put in the bed of the truck? Id like to put tape around all the sides.

If you have done this what kind of switch are you using. Id like on one mounted in the bed of the truck or right up top where the review mirror is since there is one empty slot up there.

Below is the actual tape I am using GM tape:

@mattgecko makes an awesome kit that takes care of all this for you.

 

His stuff is really nice. Fortunately for me I work in the lighting industry and have most of the material to make my own kit. Just need some help on the actual installing and speck part.

Does anyone have the install instructions?
