I commute an hour in NYC each night. My wife and I each have 2 Planet Bike Beamer 3 lights which work great in Blink mode. However, I have bought 5 Planet Bike rear red blinkers in the past year and they all dangerously have failed me. When I set them on blink mode, it takes maybe 10 blocks before they somehow switch to steady mode and then if I don't notice and quickly switch them back to blinking mode, they eventually just turn off.
Does anyone know how or why this happens?
Can anyone recommend an affordable and dependable $20 blinker for me?
