Oye. I got the cheepo air horns in from Ebay. Two metalic bells, chromed. separate compressor (size of a small soup can). Says it is not waterproof, need to mount inside. Double Oye.

then a friend mentions that they need to be hooked up with a separate switch or a disconnect switch so they won't sound when in the inspection station in NJ.

does anybody have a reference to NJ state law regarding air horns? I've been looking, but good ol' NJ is not very forth coming about requirements. (gee, I'm surprized).

Any info would be appreciated.
