Just a quick update on this rear light which I've owned for 3-4 weeks now:
Buy Smart Lunar R2 Rear Light at Tredz Bikes. £13.99 with free UK delivery
It's started to go wrong, it's been through alot on the back of the Haibike and last weekend the bike was particularly muddy so the bike was washed and so was the light, I went out last night with the light on the disco setting and after an hour of offroading it was stuck on the slow flash, I could't turn it off. When I got home I opened it up to get the batteries out which seemed dry, put the batteries back in and couldn't switch it on, when I shook the light a few drops of water came out, so it's got water inside and it's currently drying out over a radiator.
I've read a couple of reports about water ingress into SMART lights, I'm guessing this has happened here, looks like I'll need to find my receipt and take it back for a refund...........
So what other very bright rear lights are there (that are as convenient as the SMART, AAA batteries, clip on)?
