> GPS synchronized emergency lights

I actually did and whilst I can understand how ridiculous it sounds, to be honest it kind of makes sense. A large number of emergency vehicles at a scene at night can become it's own mini light show which can be really distracting / blinding.

It does look kinda cool though.

I have dealt with such a system. I'm not sure it was GPS based but one of the options you could get was a radio system so that additional vehicles that arrived on scene would automatically sync their lights and sirens to match the ones already there. The lights and sirens themselves are CAN modules and run off a custom CAN bus. It was pretty interesting to go through the configuration software and see the literally hundreds of preset flash patterns for different regions of the world.

Around here they're based off GPS plus time. To many cops got splattered because they had their lights set to day at night and the traffic couldn't see the officer.
