For turn and brake lights you can get the Avenir or clipbrite i just bought both to look at them and decide on the one for me i ordered the Avenir from www.bicyclebuys.com 14.99$ and arrived in three days i ordered the clipbrite the same day and got it just short of six weeks and a lot of phone calls/emails almost daily www. clipbrite2000.net/beamer-2000.htm both use the same brake switch that is easy to install the clipbrite looks a little nicer,i installed the Avenir.both have a sound signal when the turn signal is on both light the brake light with out turning on the unit,i think the Avenir is brighter both have 7 leds.i just installed it so i am not sure about longevety.
