I say both, too (if you have the available funds to do both). If you've already got something in mind for your handlebar light, you might want to consider a small but powerful flashlight (a CR123A or 2xAA version) as a helmet light...then you can use the helmet light as a flashlight when you need one. A few folks really like the more compact Fenix lights as helmet lights (the CR123A versions being small and powerful). I use a 2xAA Fenix on my helmet (an L2D), like the two on my handlebar, so all three use the same batteries and all are interchangeable in function, but the L2D makes for a pretty long helmet light (to some). Mine is not an overly powerful setup, but it's three lights at roughly 180 lumens each, and it does the job for the riding I do, which tends to run to the more tame side in terms of speed.
