Knog lights - kill them in the wet

replace the back one with a brighter one, rear frog are too dim for vehicle drivers to see you.

The Cateye is a rear one on the back of my belt. The frog just flashes underneath on the seatpost. Two lights on each end at different heights I figure makes for good visibility.

Even though the frogs supposedly have a decent battery life I've found mine dim quite quickly. I cycled with a friend who had just bought some new ones and I couldn't even believe they were the same lights because of how much brighter his were than mine.
