http://www.cyclingexpress.com/ send me a email with the code "12wide" for a 12% discount on all their products so I checked it out.
Found the best price I've seen on the "Moon Light X-POWER 500" bike light @$87.95 after discount code ($115.00 on ebay).
Ordered that and the "MoonLight SHIELD Rear Light - 60 Lumens" for another $26.40 after discount ($47.00 on ebay).
Code is used after login
Compact, but that makes battery life limited.
Other kits are available with the same XM-L emitter, but a 4-cell li-ion battery, for under $50 delivered.
