I know a guy that made a light under for when he's in a wheelie it shines on the road. The lights went down his fork tubes, it was neat set-up. I don't agree with any wheelies on public roads honestly, 1 wheel is less control. I doubt they were drag racing, but instead just taking off quickly because they enjoy their bikes power. I feel that if he wasn't in a wheelie he could've swerved and flipped the driver the finger probably, but that's just my opinion.
