Couple of quick points, first off try routing the V-lite UNDER the bungees on your cover. The cheap ones have a habit of delaminating from the velcro backer when they get hot. Also, try angling the light over your left ear downwards. They're relatively short throw and quite directional so if you want to use it to see where you're going you'll have to look down a lot, a bit of downward angle will help you maintain your forward field of vision (although I would suggest the mandible may well obstruct your downward field of view anyway).
