Hi Tim and welcome to the forum!
I don't have a TS but these handles are usually lighted by a bulb mounted in the chrome mounting bracket and out of sight. I think they're usually a pretty standard size item too because my Itasca didn't come with one but I bought a replacement bulb from a Monaco dealer and wired it myself. The bulb just illuminates the clear acrylic handle.
Good luck... we're glad you found us.
