Well, I"m not sure I'd call it the same type of strip lighting. They have a long PCB with fewer LED's, I found that having closer spaced LED's that each were not as bright gives much more even lighting. I actually did lay out and get a prototype of a PCB, but it seemed it was easier to customize with the strips, so that's the way I went. With the strips, you can cut them down for short 12" cars without any problem, or install them in 21" cars full length.
I'm sure either approach yields a good conclusion, I just decided the way I went worked better for me.
