Review: Lezyne KTV light combo

Hi all,

I just wanted to give a quick review on Lezyne's new KTV lights, a matched set of single LED front and rear safety lights.

These are small, compact, USB rechargeable lights that use a rubber strap to secure to the bike, or the integrated clip to mount on bags and clothes. The strap system is really handy to use; for switching between bikes or simply removing during lockup, it's tops. What's clever about the system is that the strap mount integrates with the clothes clip, so both options are always available, and you're never left wishing you'd remembered to bring the mount or the clip. Additionally, the rear unit has an asymmetric indent where the clip would meet the seatpost, which keeps the unit aimed level out the back, rather than angling downwards.

Unfortunately, like most clips for lights, hanging it on a light loop on a seat bag or piece of clothing means it's probably dangling limp and poorly aimed. I don't necessarily fault the lights for this, but rather the bag manufacturers who don't make more stable mount points.

Working the lights is straightforward and easy. The power/function button is placed easily at hand, atop (or at one end, depending on orientation) the unit, and the detents are clear. It has, IIRC, Five light modes, but no "last mode memory," so you have to click through to return to last used setting.

The modes include the standard slow and fast moded, but also has a pulse mode and low powered solid and a high output solid.

The single LED is rated at 15 lumens, so nothing major, but hopefully enough to grab some attention. The lenses protrude from the body, providing some side marking bit they also focus the light in a wide, narrow pattern.

The lights can be oriented either horizontally or vertically thanks to the rotating clip/strap mount. The bottom rubber portion of the unit pulls off to expose the USB stick; very easy to use. There are also charge level indicators always illuminated on top of the unit when it's powered on or charging, so easy to know where you are chargewise.

My impressions of the brightness are favorable, though it's certainly not the brightest thing out there. I feel they add an extra margin of safety for dreary day rides and are more adequate when it's dark. I bought them primarily to use on my winter bike for 2-3hr rides on overcast days, and I wanted something small and unobtrusive; these work well in that regard.

I was particularly delighted to be able to mount the front horizontally on my steerer tune under the stem, since my bar space is eaten up already.

Overall, I really like these (1 ride in) and thin for the mid-$30s pair price that they're right on target. I'd have preferred to stick with the much brighter Knog Road R tail light, but I've had a rash of bad episodes with that light's quality and durability lately, and at roughly $50 per unit, was feeling the bite and wanted to give something else a go. I'll elaborate on the Knog issues later, after I hear back from them (if I do), but these Lezynes seem good enough and better in some specific regards.

Here's a quick pick of the froNt KTV under the stem:
