Cateye Viz Rear Light

Product Information

The 15-lumen steady is up to the job of built-up areas; I seemed to register on friends' radars at 70-80 metres. Run-times Positioning it vertically has a small but palpable edge, especially at junctions, negotiating roundabouts and just performing turns in the road – particularly so when I've tethered it to my low-slung trailer. Though it has a smaller surface area than I'm usually comfortable with attaching to a trailer or tagalong, the daytime mode more than compensates, especially in such contexts.

The shortest claimed run-time is a useful 5hrs, and that's pretty accurate – surprisingly it's not for the eyeball-grilling 300lm 'Daytime Hyperflash,' which can signal nearby planets (probably) for up to 10hrs, but for the 30lm Constant mode. The Group mode is next in line for output at 50 lumens. To be honest, because its flash pattern is so much more sedate it actually seems brighter, but it's a bit too much for those sitting on your wheel.Steve described this mode on the Viz 300 as luridly chaotic and it is – it's not just the bonkers output of those bright flashes but all the various rapid strobing that's going on at the same time, which makes this hard to ignore. Following behind this light in the daytime, I found that from around 100 metres it was very effective at being impossible to miss (and not overly bothersome) but from 10 metres it was pretty irritating. I didn't ride with this mode at night, so cannot report the thoughts of other road users. I would only use this mode if I was doing a lot of riding on fast A-roads in the daytime, and it would make me feel safer in that specific environment.

Cateye's previous Rapid range of rear lights offered excellent all-round visibility using a line of LEDs that were visible from the sides and the rear. I still have some that I tested six years ago and they still work fine, which is a decent innings – other brands' lights have not lasted nearly as well. I also avoided the Daytime Hyperflash in anything but strong sunlight, because it's so bright and so luridly chaotic it's like riding around on a distress beacon. Again it's a personal choice, but I don't want to give the worst drivers another excuse to throw a cretinous shut-your-eyes pass.

The ladder strap hooks into lugs either side, and I've had no issues with standard round profiles between 25.4 and 30.8mm. It's compatible with some box-section trailer tubing and helmets, too.As the name suggests, Cateye's Viz 450 rear light can throw out an extremely bright beam, although the full power is reserved for an intermittent flash in the 'Daytime Hyperflash' mode. In some specific use-cases you might appreciate this amount of power, but for most cyclists it is overkill and potentially a little provocative. There are more socially acceptable modes, but you could also just buy a less powerful, cheaper light.

That doesn't sound very bright, but the 30lm glow from all three LEDs through the transparent case is actually pretty eye-catching outside of bright sunshine or night-time commutes. ViZ100] φ21.5-32.0mm. Fits up to 130mm outer circumference. (SP-15) Recharge/discharge number of times： about 300 times（until the rated capacity drops to 70%） Water resistant： [AMPP200] IPX4 Happily, there are less bright, less expensive options from the same range, and for my money the Viz 100 at half the price would be all the light I'd need. VerdictOr buy a Rotlicht instead, where you can replace (and recycle) an exhausted battery. I'm getting the sense that you can't do that with the Cateye?
