“Both lights ( mainly head light) seem to lose power quickly. I had to recharge them after 2 hours of use. The headlight indicated full charge(3 green lights) and after a 2 hour ride only 1 green light was on. The light was on charge overnight before the ride. I had the headlight on full beam with a pulse. Normally I have them on flashing. Will try the flashing mode to see how long the charge is retained. The rear red light appears to be somewhat better as I only have flash mode.”
