Hard to believe that I was so smitten with my light just a few short weeks ago. I went to turn it on last night after a very long 12 hour day at work. I was beat. I clicked the power on...nothing. I tried to unplug it from the battery, replug it in, pushed the button several times all with no success. COME ON! It's nearly 9 p.m. and I have to ride home in the flippin rain, again, now with no light? How is it that my $25 Cat Eye rear flashing light has made it through 3 cold winters, dozens of rain storms, dirt, grit, dog sh*t and every other road debris thrown at it and it still works (very well I might add) but this $150 light with three less settings mind you, kicks the bucket in under a month? I hate all lights. They have been the the ultimate weak link in my commuting experience for as long as I can remember. I don't know who these manufacturors think they are. Do they do any kind of testing on these things? And no a spraybottle in the lab doesn't count as "weatherproof" testing. This thing is going back. I need a light that I can use every day without failure.
I was actually enjoying the battery life on this thing before this happened. This night rider will be using his mountaneering headlamp for a bit. Not cool.
Sorry to hear about your light woes. Nothing ruins a day faster than unreliable gear. If you give up on that light you've got, you might give TurboCat a try. Their setups have absolutely nothing in the way of features (you get an on-off switch, that's about it), but they choose to spend their money (your money) on something much more important: dependability. Check out their web site. I've had my setup for 10 years. Used it for mountain biking and commuting in winters in OR and ME, both states that dish out all forms of cold, wet, gear-destroying slop. I've replaced the battery twice and the bulb once - perfectly acceptable maintenance for a decade of use if you ask me - but I have never ever had a failure.
See you on the streets!
