John,
Didn't you have a advertisement on your web site on the LED trail light that lets oncoming riders know that you have more riders behind you or that you are the last one in that group. Have a 12 year old son starting this year and I believe it would be safer for him to have this than using hand signals. I can not find any info, can you help me out.
Thanks
.

John, Found the web site ( http://www.communicationsafetysystem.com/home.php ) and if I confused anyone since the leds are just yellow and green sorry.
