I put a dash 350 on my seat stay through a tunnel last week. A Planet bike blinky, a Cygolite hotshot 30 and a white dash 350 in blink mode. Guess it worked.

I have read that an amber reflector is visable at 6 times the distance of a red reflector. Is that true of lights or not?

Today, I compared a Serfas tunderblast, Last years model, and a hotshot 50. In the day light, the Serfas was far more visable from rear and side. After dark, the Hotshot out shinned the Serfas by a considerable amount.

Day lights are a good subject to learn about.

At the moment I am interested in getting front and rear lights with removable batteries. Why? Airport regulations. They change from country to country. In Mexico they want the batteries removed from the device and in a checked bag. In the US they want the batteries in your carry on.

My next couple of trips depart from the Tijuana airport and South.
I need lights for safety, and to get out of a jam. Hotel was further than I thought, no flat spot for the tent. Nothing fancy, I avoid night riding if at all possible.

This evenings ride was with a mitycross 800 OSP, I would hate to lose it to airport regulations. Same with my Niterider 1800. To me bike touring means usb recharable, or AA AAA in my solar panel.

So gents and ladies, oh and cats, any ideas for AA AAA lighting system?
