I've done it as well... Hella dual air horns. It still doesn't wake up some people. Too easy to get and keep a license in Oregon. A lady in a Suburban nearly had a head on with me because she was too busy chatting on the phone... crossed over the yellow line. She got the wake up call but continued on like nothing had happened. I guess she's done it before.

Definitly read the lighting FAQs I linked to in my other post before spending your money on bulbs. It pains me to see people spending extra for those Honda Boy blue light specials.
