I started making my own LED strips several years back since I can make one for about 1/10 of the cost of any equilivant commercial light strip. I get the LED light strips on a reel and then mount the length I need onto a section of the right angle acrylic wallpaper corner protector available at Lowes/HD. I then mount a mini push button switch that you can buy in bulk on e-bay that are basically flashlight button switches.
I've made strips for my entertainment center (on a dimmer with remote) and several window curtain valances (simple on/off switch) in the trailer along with floorboard lighting and trunk lighting in several vehicles.
Doing it this way I can have the exact length and color LED lighting that I want and in one vehicle the LED strip is dual color one on the vehicle dimmer ckt to match the OEM dash color and the other bright white for good visibility in the floor area when needed.
