From Thinkgeek:

While we get our bikes out of storage, we’d like to introduce you to the Knight Rider KITT Car USB Charger. The Knight Rider KITT Car USB Charger has two USB ports, each capable of charging almost any USB-powered device (both put out 1.0 Amp). But it also has that signature light sequence from KITT’s voicebox we all know and love, synced to respond to 11 different audio phrases from the TV show. And in case you ever need less 80s, there’s a switch to turn the whole thing off or mute him. Possibly so your smart-mouthed car doesn’t speak to the nice officer.
