🚴 Serfas Thunderbolt 2.0 120 / 50 Light Combo: Brighten Your Ride with Dual-Intensity Lighting Review

I feel like it makes my rides a little safer. The front light is not bright enough to act as a headlight, but makes you more visible to drivers. They appear to run for the nominal number of hours (although I charge them before they expire). Clips and groups work very well.

Great rechargeable bike lights. Excellent battery life, multiple lighting settings, always on, multiple flash brightness options for day and night. The only thing missing is the mounting setting. You can only direct the light onto the base in one direction and not in two, i.e. along the XY axis.

Very small and narrow, but the bracket is quite wide. It's bright enough and the battery lasts a lot longer than the original Thunderbolt, but the mounting system isn't nearly as neat as the original. Basically, this version only surpasses the original in terms of battery life and real-world size, but the mounting system ruins its smoothness.

I ordered this Serfas Thunderbolt 2.0. While the box is duly labeled Thunderbolt 2.0, the product inside is a similar but different Thunderbolt model. I have another set of Thunderbolt (2.0) and you can see the difference between one and the other. Both work with the same lumens and modes. However, the 2.0 is smaller and slimmer. I am disappointed in this inconsistency. To make matters worse, I have to pay the shipping cost to return the product. accidentally by Bikewagon. Not cool. Confound.

The previous version was my favorite bike light system. I like this version even better. Separate attachment straps allow them to remain on the bike while the working portion of the device (shown in this image) is removed for charging. No more fiddling with straps for occasional charging. Install fasteners and forget about them. The charge feedback mechanism (flashing blue light) is OK. This version seems to load faster than the previous version and the actual runtime is much longer, especially
