The most common failure mode for battery lights is lack of battery capacity - either disposables that have drained, or rechargeables that haven’t been recharged. Generator lights are typically more rugged. It’s not uncommon for parts to dislodge upon hitting a bump.
Many battery lights are comparatively flimsy, often held together by plastic snap tabs, and clamped to the handlebar so they are easily knocked out of alignment by a hand or knee. Battery lights tend to suffer more problems with bad connections, especially internal battery contacts or external cords that are frequently plugged and unplugged. Generator electrical connections are usually permanent. No battery waste, no hazardous materials. There's no need to remove your lights and take them with you when you park your bike.Įnvironmentally friendly.
If necessary, theft-proof fasteners can add even more security. Generators and their lights bolt onto the bike, but clamp-on battery lights can be unclamped by any passing pilferer. Want to extend your evening ride? Traveling and unable to recharge your lights? Or just don’t want to bother with battery charging, battery replacing, or remembering to take your headlight? No problem.
