These little lights plug into each end of a road handlebar and shine a white LED forward, with red LED in the rear. That's not the only cool part, though. Each side has a little button for a turning signal. You reach down, hit it and it will flash yellow for a few seconds and then turn off automatically.
This is a new product for us, so we don't have any information on long term durability. It is a very interesting and unique light, though, so we thought it would be worth trying. We would be very happy to get feedback from you.
