I may just be picky, but it really bugs me when ANYBODY says any product or feature is "OSHA Approved"...OSHA approves nothing. It "might" meet OSHA standards, but that would take some proving to me, if it's not manufactured here or for direct import to the U.S.
In a lifetime, the average driver will honk 15,250 times. My wife figures I'm due to die any day now...
