Do they exist?
So far have killed 3 Flea lights (originally won on here via Schwag grab) - Madison stopped responding to emails sadly, so lifetime guarantee not up to much there. Which is a shame because they were fab lights - just not waterproof.(Front light is fab and appears to be waterproof - maybe I shouldn't say that probably kiss of death )
EDIT: actually that is 5 Flea rear lights die. I had three sent back to madison, and I've got two knackered ones on my computer desk
Killed a Lumicycle rear light - which again surprised me.
Have killed off virtually the entire recent range of Cateyes.
Best light was a Vista - yonks old, bought from Freewheel many moons ago. That lasted and lasted until it fell off and fell into a grid.
Any others worth looking at, or do I have to face upto the fatc that nobody makes a light that will survive on the back of a bike day in day out with British weather?
