I do not know exactly what you are trying to do. But if you are wanting to make easy color changes, like the surrounds around the led lights you can use the colored electrical tape. I use the red on two different places on my SS where wear or gravel messes up the paint. There are many different colors to chose from. For anyone that does this "DO NOT STRECH THE TAPE" when you are doing this. Just a though that may help some people. One place I use the red is where the back of the hood rest on the short colored piece by the wind screen and rubs the paint off.
Not sure colored electrical tape would allow enough light to penetrate effortlessly through it... but I like the idea!
