So my second serfas thunderbolt is now nonfunctional due to a little bit of rain on my ride today:notamused: I had this issue with my first serfas and the lbs just swapped it out and said it happens sometimes. Well this one is literally about 1-2 months old and I am talking MILD rain.
Suggestions on a new taillight?
must last 2+hrs. Must be rechargeable,preferably USB. Must last in crappy weather 15F-100F and rain.
