There is a wonderful light that is ultra bright so that cars will see you and acknowledge your existence and won't run over you. It will save your life.

It also has much better runtime, and better durability than the Fenix L2D Q5 that everyone is barking about.

It is the Fenix TK11, the tactical light, that uses 18650's!
Put a pair of these on your handlebars, and you will be seen by cars, and they won't take your life, you will be protected and safe

couple it with a pair of PlanetBike Superflashes, and you are gold!
