When cycling at night, even with a red light on the back of your bike, drivers may not see you because you occupy only the edge of the road. I propose a laser, mounted under the seat that projects down, back, and sideways onto the middle of the traffic lane. It vibrates, so instead of a spot it makes
a circle on the road.
A motorist approaching from behind will see an area of light directly in his line of sight.
(It does look like a little laser coming out your ass, but that will only make drivers pass with extra caution.)

Interesting...I think the link helped clear up some doubts I had. All in all I give this a plus. |

How about an upscale version with laser show technology so you get this on the road: |

a (+) from me, but extra delight if you can spell out useful words like [krelnik] suggested. |

It could also make a circle around the
bike. + |

"Burning Ring of Fire", more like!. + |

"Bicycle Butt Laser™ -- It Will Save Your Ass" |

A half-second earlier in the illustration, the laser was shining on the side of the van. Don't light the street, light the rider. Point your vibrating projection at the back of the bicyclist. He may need a reflective patch on his back (or butt, whichever is larger) for effective illumination -- after which, he won't need the laser anymore. |

Nice one, [AO]. Good to see ya. |

Only if it was head-mounted. |

Use a green laser for better visibility (apparently the eye can see this more easily). That's why green laser pointers can be seen going through the air, but the power rating is not over the recommended limit. |

isn't red a more appropriate tail light warning colour? |

Worth baking. You could make a small fortune. Ahem, ah, nevermind. Could someone show me the way to the patent office? |

"Golly Mildred, what's that green arrow in front of us mean?"
"Uh, it must mean we're supposed to move over into the right lane." |
|
| |
"Golly Mildred, how'd you get your drivers license?" |
|
| |
Mmm - I can see fully-fared sports bikes with sprays of pulsating colour surrounding them - shooting down highways like multi-coloured suns. |

Hah, you could have some fun with this:
"Bus lane"
"Stop"
"No entry"
"20mph"
"Give way" |
