Rich Lieber
Good Taillight

Taillight has multiple settings for different conditions. First one received would not hold a charge, but was exchanged by Aventon without a problem.

Hey Rich,

Glad that we were able to help make this right! Safe travels to you and your family during the holiday season!

Happy Trails,

Being seen

Works really well, people seem to be giving me a pretty wide pass around, and thats a good thing. I believe it works as well in the day light as it does in the dark.

Yay! Glad that this was a match, Gene!
