CAUTION: I'm sure most of you heard about the "Green Light Trigger"........STAY AWAY FROM IT! I got one and it didn't do JACK $]-[!T. All its good for is collecting rust. not even a week after i installed mine(bottom fairing under the exhaust pipes/oil filter,zip tied to the metal bracket that holds both side of the fairing together) all i got was rust from the magnet itself! yanked that POS off since it didnt made a difference(atleast not that i've noticed). IMHO, you can use a magnet from any speaker and it should work the same(if it even works) just try and find the strongest magnet you can to have a better chance of it working. I've been trying tons of different types of magnets but found none to my satisfaction yet. i'll update you guys if i find anything. FYI, try and go to an ARMY SURPLUS or better , go to AMERICAN SCIENCE AND SURPLUS(if you have one where you live) its a good place to find just about anything!
