Query: Excellent value, good brightness, lacks common charging port.

I'm wondering if these are an older model as they use a mini-usb charger as opposed to the now ubiquitous micro-usb that powers most cell phones, bluetooth speakers, and other devices. That's the only thing keeping these from being a 5-start product. Lots of flashing modes on both lights, combined with great battery life out of the box (if these are older, we'll have to see how those hold up) make this a winner. The headlight mount is a little bulky and can be tough to route under cables and other items in a crowded cockpit, but still a great value for the money at the price I paid on sale.
