Riding off road at night requires a good headlamp and fortunately the days of massive battery packs are a thing of the past. The new Trelock LS950 from Cantitoe Road offers six hours of full brightness of 70 lumens, but also features five power levels for those times when a little less light will still do the trick. This means up to 45 hours of run time in between charges.
It has a somewhat sinister look that kind of resembles the Alien from those Alien movies, but perhaps that will just creep out the competition. More importantly, the rechargeable light attaches tool free to a handlebar offering an easy set up and plenty of time. You do need time to sleep after all.
