don peacockwrote a review of Blackburn Dayblazer 125 Tail Light on February 10, 2019
Familiarity: I've used it several times
don't like the run time, put it on lowest level and was dead before 3 hour ride was done. Charging again, will update.
Update: seems like the more times you charge it from totally dead, the better it gets, nice bright light and is o.k. now.
