My new toy is a Fenix LD20 light that I attached to my helmet with a couple of my daughter's pony tail elastics. Plus Eneloop rechargeables.

I have been commuting for years using a pretty simple set up of an old PB Alias 10W headlight and a Super Flash rear. It was enough for my needs -- pitch black MUP 90% of the way, easy enough to be seen and don't need much to see since I'm not competing with too much else (king of night vision, king of insight). But I do like the helmet light as an add on to spot stuff off the path (e.g. deer, perverts) and to make brief "eye" contact with motorists for attention when I'm not on the MUP.

I had been seriously pondering a MagicShine upgrade and was about to pull the trigger when they started going up in flames.

I think if I go large in the future it will be to Dinotte.
