Based on the original by Dipper, I wanted to play around by sequencing the lights to replicate real police car lights. All lights are enabled by default, plus larger headlamps, working brake lights and proper reverse lights with a little trick.

As for the sequencing, I know it's a bit off - for some reason, the value 0 (in the XML) still counts as a duration even though it shouldn't (the sequence is "onduration,offduration"), so I set it to 0.1 to even out (in other words, some lights flash three times instead of twice).

Other things, I disabled front brakes for a bit of drifting fun and altered the controls. Pitch and Roll/WASD for maneuvering. Enjoy!
