Query: Very visible and easy to maintain

I ride 21 miles per day in the early morning hours before daylight and this tail light has been one of my favorites over the years. It is very visible from quite a distance and is easy to swap out the batteries. My last Blinky lasted about 3 years without a problem, which is pretty good considering the amount of use this gets year round. I would give the light 5 stars but the newer version comes with skimpier attachment hardware which required me to improvise with electrical tape to get it to fasten securely to the frame of my Trek carbon fiber bike.
