Wowza. Got my new headlamp today. It's a Black Diamond Sprinter. I may have unintentionally burned my retinas with it. It's pretty darn bright. Plus, it has a rear taillight. I'll have to test it out as soon as it gets dark. My other headlamp is a BD Spot. We bought it mostly for camping, but it just wasn't up to the task. I recently bought a reflective harness and some reflective leg bands. Anything else I might need for safe night running?
