Also, works great when you have to work on the bike in the dark. Mine has a flasher/red in the rear as well.
Same here, I also run one facing forward on the handlebars that is usually flashing. This gives me a back-up should one of them have its batteries go dead en route. I also like that when I turn my head I still have a light for visibility facing forward.
In addition to the helmet lights (Planet Blaze .5W helmet mount light & Planet Bike rear helmet flasher) and the handlebar one (1.7w flash-light in a bicycle flashlight holder), I run a rearward facing Mars 4.0
That's what I recommend.
In addition, I run a 1 watt Fenderbot on my rear fender and am experimenting with a fairly powerful (3w) flashlight in a mid-fork mount to better illuminate pot holes. At times I commute regularly both ways in full dark.
