Serfas Headlights Editorial Review
The Serfas Thunderbolt 2.0 120 50 Light Combo is a solid choice for those looking for a set of bike lights. The front light is bright enough to make you more visible to drivers, but not enough to serve as a headlight. However, the rear light is plenty bright and both lights have good battery life and multiple settings. Charging is easy with the detach clip and micro USB charger. Installation is also a breeze with the clips and bands provided, and no permanent installation is needed. The only downside is that the mounting system on the newer version is not as sleek as the original.
