There is a small, recessed pin size hole for a red light to show when activated. I like the price and while its not overly attractive, its perfect for the basement. really disappointed particularly as the price is reasonable high and the make is meant to be of high standard Those considering these, don?t think about it twice just purchase them you won?t be disappointed, they are worth their price. I looked at numerous standing towel racks on line and decided to try this one - it was the perfect choice for my space. So be sure to check your purchase to make sure it works for you before the return window closes. I bought the black MegaBlast. The only problem is how difficult it is to get them on wihen worn with socks. This is not something that is even remotely tolerable in FPS games. I watched the instructional video, and didnt use the paper instructions.
