I am looking to supplement my current Magicshine 900 lumen handlebar mounted headlight and Bontrager Flare rear light with a helmet light. My riding consists of 75% commuting on local paved trails with a short stretch along a paved shoulder and 25% mountain biking. My main focus is for a helmet light so I can see better when I am mountain biking, but I would like to be more visible on my commute as well, though I don't often deal with a lot of traffic. I would prefer it to have a front and rear light in one and I would like it to stay around $100 or less.

A few I have seen that I like the designs are the VIS360 from Light & Motion Vis 360 - Light & Motion and the Lezyne Macro Duo Lezyne - Engineered Design - Products - LED Lights - Macro Duo

Any other recommendations would be greatly appreciated. I'm not sure what to look for as far as Lumens.
