experiments with LEDs for rear lights

[trevor brooker]

This was taken at 50m, showing wilkinsons high intensity led at top, with a normal bike led underneath and my experimental LED strip lights.
When I have followed other cycles I thought that its the size not brightness that draws the eye.
So using 5V flashing LEDs I mounted them onto my rear carrier. My rear carrier bags obscure my legs, so putting flashing leds on my ankles will not work.
I was hoping to achieve something to show that a bike is wide & not a wheel with lights above.
The led strip is mounted onto reflective tape, so a cars head lights will emphasize it.
if interested I will post more details.

Are you sure that isn't a Volvo?

Great idea.
I have a rear light with red Laser LEDs that projects red lines to both sides of the rear wheel, wider than the bike...

I hope this "drives you on!"

I have only seen pictures of those Laser lights, and did not know if they would work over a rear pannier. What is your experience with them?

Good question, I made up a simply bracket and attached it to the rear of my Pannier box with a single wood screw, so the lasers miss it and my "side saddles" as well...
It was made out of a piece of broom handle!
