Lifespan of the lights?
Not talking about battery life. I'm interested in how long, after you bought the lights, the lights themselves can function--the regular battery (such as AAA or AA) operated, headlights and taillights. I suppose the leds or the bulbs can burn out after too many uses? And if your lights are subjected to rain more than a few times, it may also affect the working life of them?
For how long have you used the same lights? After more than 1 year and rare rain rides, my lights are still fine. Anyone's lasted many years with regular riding?
