Title: Just buy a few feet of string and a ping pong ball
Review: I bought this because I thought it was a clever idea, inexpensive and was easily movable for different vehicles. Like so much junk made in China these days, it's a good idea ruined by poor quality. My problem was that the lights refused to come on unless the pole was bent nearly horizontal. Pointless, since I would have to be drunk to drive that far over it, and I couldn't see the lights anyway because they'd be blocked by the hood. As the other reviewer said, you don't really need the lights because it jiggles when you bump it, but I can achieve that with a length of string and a ping pong ball hanging from the ceiling.
