Downward facing white lights for safety
My taillight hopped off 5 miles from home at the end of a 500 mile tour. It was dark and the road got narrow and unlit so I strapped my flashlight to the left seatstay, pointed down, illuminating the roadway.
Looking at the result, I thought it did an absolutely great job of improving (creating?) visibility. A useful product? A legal product? A marketable product? I have searched a few times over the years but found no mention of such a product, nor such a use of a light, nor any patents, nor laws regulating or prohibiting downward-facing lights. There are however as you know a lot of laws about what lights one can have on a vehicle, what color and direction and distance they go, and I wouldn't be surprised if it's illegal I just haven't found it yet. I think it adds a lot more visibility than a red blinky. dkl |

I have searched a few times over the years but found no mention of such a product, Doug, I think Rock the Bike were the first to popularize that, with their Down Low Glow: http://rockthebike.com/the-down-low-glow/ Under some conditions it's excellent for visibility--but it's always a lot of fun at parties. -- Gregory S.

There have been some downward facing lights recently https://www.wish.com/c/55fbaa522ad06e1c199db3e1. |

The Act specifies that the rear light MUST be red. Years ago in the days of the Belt Beacon even that light did not make a bicycle road legal due to the factthat the lens was amber not red. the police told me to stick a red reflector somewhere on the rear of the bike and that'd make it legal. The Act stated a red light OR a red reflector. Then again, legally here, bicycles are supposed to have strips of white reflective material on each front ffork leg and red reflective strips on the rear seatstays. I figure that almost any light on the rear of a bicycle is better than no light on the rear of the bicycle. Cheers. |

I think it adds a lot more visibility than a red blinky. I'm curious how you tested that visibility. Did you have someone else evaluate it for you as you rode? Or did you observe it from a passing car as someone else rode your bicycle? I think some strategy like that would be necessary to do a reasonably accurate evaluation. BTW, Sir is right. At least in many jurisdictions, rear lights must be red. You could easily make yours red, of course. -- - Frank Krygowski |
