These kinds of things have been around for years, but I still want one. A while back, there was a device that would change the signals based on the strobe frequency of emergency vehicles. The device would register the strobes and turn the lights. Someone bought a 5 Dollar storbe unit and added a pot so he could tweak the frequency, and whala. Instant light changer.

The first IR emmitter hack I heard about was years ago with a Mucipal bus line. The Express line had an IR device similar to that above. Funny thing was that you could take a learning IR remote and point it at the bus and "learn" the signal. People were pointing TV remotes at lights and changing them. I think they changed the frequencies since then.

I'd be happy with just a radar/laser detector. And maybe a GPS. That light switcher would be really handy on a motorcycle which usually isn't heavy enough to trigger the weight-sensor on the "smart" lights.
