Rock Lights kit Recommend?

Looked around a little and didn't see anything that really answered my questions. I was looking at rock lights for my car, since they came with a musical strobe capability. Is there anybody out there that has used these?

I think they would cool for illuminating sliders or steps for people to get in and out in the dark or changing a tire. I found some rock lights that look good. What do you think？
