Cut your losses.
You get what you pay for, and with Light & Motion bicycle lighting systems, you get a lot. Fortunately, a nasty spill doesn't have to mean the end of the world, even if, after dusting yourself off, you realize that you just completely nuked your headlight. Light & Motion's Seca 800 Light Head makes it so you can replace the headlight's meat and potatoes without having to pay for a new battery, mounting bracket, and charger.
The Light and Motion Seca 800 Light Head comes with a 50in power cord that allows you the freedom to put the battery in a variety of locations. With the handlebar mount, hang it on the top or down tube. Use it on your helmet and stuff the battery in a jersey pocket or a backpack.

How does this compare to the TSL-1000? Obviously need a battery here, but output (and quality of output) wise, battery life, etc.?
This is a much nicer light than the Serfas, but its also more in price. The L&M is made in the USA and a high end brand as far as lights are concerned.
