Levels the playing field
From Michel Kurita of Ottawa, Ontario on 9/18/2008.

I purchased a Dinotte amber daylight visible light a week ago, and I mounted it as a tail light. I believe a flashing amber light is more effective than red for tail lights because:
a)The unique colour stands out in a sea of red car tail lights
b)Amber is more visible to the eye
c)Amber means "caution"
d)Flashing amber means "slow moving vehicle"
e)Flashing red just means "prepare to stop" and if the purpose of a flashing light is to catch a drivers attention, then amber is much more effective at this.
f)This light is close to 130 lumens - my previous Planet Bike Superflash tail light is probably 20 to 30 lumens. Therefore, my tail light is as bright as a Lexus RX L.E.D. rear light array, but the Dinotte is more visible as it is amber. I also have been using 2 Planet Bike 1 watt L.E.D lights on the front (they are probably close to 100 lumens together - <i>just</i) visible during the day head on). I'm planning to upgrade this to 300 lumens.

The result has been that drivers no longer wait to make room for me at the last minute - their passing maneuver begins earlier, and they remain in that position, leaving me with a "corridor" lane as I approach a red light. Not one driver has tried to pass then turn right, right in front of me. I have not heard one obscenity, even though I know if you stare at the light, it is quite blinding.
