Video, or it didn't happen!

(Just kidding. )

Good mod.

When I was a teenager driving my parents' giant Caprice station wagon around, it pissed me off when people pulled up directly behind me a few times when I stopped on the street to reverse into a parallel parking spot - even with my reverse lights & turn signal on. I beeped the horn a few times, hoping they'd get the stronger message, but they didn't (because the horn was in the front of the car, half a block away!).

So I installed an extra horn under the rear bumper, "pointing" backwards. Horn mods are fun.
