Very cool! I love getting stuff for free. We both (Kitsune and I) have the single MiNewts and just love them. Incredibly bright, the battery pack is so small but holds a terrific charge. Very easy to get on and off if you need to. No bad reviews from either of us on this one.

As for a rear blinky, try the Bike Planet Super Flash. The battery lasts forever before needing a new one and that thing is nasty bright and gets loads of attention from motorists.

Have fun with your new lights! I'm curious how you will like it with two beams...
