Nice practical rear light with a built in failsafe

This neat little light from Portland funsters PDW won't win you any prizes in the great rear light arms race but it's a useful safety aid nonetheless.

PDW do good names and there's a clue in this one. It attaches to your mudguard rather than the seatpost, which means it's impossible to forget or lose. If you have mudguards with a reflector already fitted then you're in luck, just unscrew it and fit the Fenderbot using the holes. If you don't have holes then you'll have to drill some and PDW have kindly printed a template on the packaging. The only downside of this extra security is that you have to unscrew the front of the light to replace the batteries, but that's not such a big deal because this isn't a honking great space laser and two AAA batteries will last a claimed 200 hours.

As I've hinted, this isn't the kind of rear light that fries eggs at a hundred yards and inspires epic 'but is it safe?' debates on cycling forums. It's a pretty modest single LED sitting on top of a large reflector. PDW don't say much about the reflector but their bigger Radbot 1000 light has one just like it and that is, apparently, 'EU compliant'. With the LED rocking its thing (flashing or steady, no silly bossanova patterns here thanks) the reflector is pretty much irrelevant but it's good to know you have it, just in case.

Urban cyclists might be wanting something a bit more eyecatching, a small LED somewhere below knee height isn't going to cut it in the neon jungle, but long distance types will certainly appreciate it. It's plenty bright enough to keep you visible on country roads and it's not going to distract, enrage or hypnotise anyone riding on your wheel, very important on group rides and longer audaxes. Back it up with something a bit sharper on your seatpost and you've got an ideal rig for all types of riding.

It's not cheap but it feels solid and shows that a rear light doesn't have to be a FRIKKIN LASER BEAM to be effective.
