I recently bought this headlight/tailight combo from Nashbar and am very pleased with it.

Niterider Lumina Micro 450 / Sabre 50 Light Combo - Exclusive

I already had another even brighter Niterider headlight, but had been riding with PB Superflash (prob .5W) and Radbot 1000 tail lights.

The tail light in this combo set is very small and very light - way lighter than say the Radbot 1000. Before I turned it on I wasn't expecting much...but I was wrong. It's much brighter and casts a wider light than the Radbot or the PBSF. There are several modes - three different blinking modes and also two or three solid modes.

The headlight is more than adequate for my needs riding early mornings or into the early evenings. My other Niterider is a bigger heavier headlight, but this new one provides enough light that I don't even put it on high - usually use it on one the lowest of the main three setting (not the "be seen" setting).

There are similar Niterider combos for a bit more $ - but I like the balance of this headlight. My larger Niterider headlight has a tendency to slowly tilt forward if it's secured on a round part of the handlebar. The one with this combo is shorter and smaller and doesn't seem to have that tendency as much.

Anyway - for $50 this is IMO a very good combo for anyone looking for lights. USB rechargeable, and the charge seems to last a long time.

I have used the no-name headlights from Ebay/Amazon that have external battery packs. They provided adequate light, but the batteries didn't last long and relatively quickly could hold less and less charge.
