NiteRider Sabre 80 Rear Light



A decent little rear light with peripheral lighting, albeit limited

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The NiteRider Sabre 80 is a slimline 80-lumen rear light with daylight flash modes. Featuring six modes altogether – three constant, three flashing – it has good options for keeping you visible, along with useful run-times: 10 hours 30 minutes on low flash, 1hr 30mins on the constant brightest mode. Amber lights boost side visibility, but this is limited.

Out-of-the-box, the Sabre 80 light comes in three parts: the light, the seatpost strap mount, with a combined weight of 30g according to the Scales of Truth, and the micro USB cable for charging it.

The light itself has a neat and slimline design, meeting the IP64 standard for water resistance (showers and splashes) so the UK weather shouldn't get into it. I used it on rainy days and also stuck it under the tap and it survived no problems at all. It has a single button at the front to click through the six different modes, and this is a good size so is easy to use with gloves, which is great as some lights are a bit fiddly.

The light is made up of a strip of multi LEDs and gives out 80 lumens on full power, which is more than enough for being seen at night. Some light is emitted out of the side as an amber colour, but this isn't as bright as the main light.

The six modes are three constant and three flashing, in bright, medium and low settings. To switch between constant and flashing you hold the on/off button for three seconds.

It has a mode memory too, which is useful, powering up in the same mode you were in when you turned it off.

While testing, I was told that at night the flashing mode grabs attention, and I've certainly felt visible. The side lighting isn't so attention grabbing, but certainly better than nothing.

Run-times & charging

Run-times are quoted as 1:30hr for the solid bright, 3hr for medium, 4hr for low; 4hr again for bright and medium flashing modes, with the low flash lasting for 10hr 30mins. They're pretty accurate too: at 1:30 on solid high the charge indicator started showing the battery was low, and on the low constant setting it managed another half an hour. On the brightest flashing mode it ran for another 20 minutes with the red warning light showing.

Charging is via a USB port at the bottom of the light, kept safe from grime with a rubber plug. Charging is quoted to take an hour and a half; I charged it through my laptop and it took just over two hours from flat to full, with the on/off button turning blue when charged. A red on/off button means the battery's low and needs charging; blue is good. There is no in between.


The NiteRider comes with a good solid seatpost mount including a strong rubber ladder strap that's easy to get on and off, with different holes for any size seatposts. There's a clip integrated into the back of the light if you want to attach it to a saddle bag or clothing. I used it on my saddle bag and the clip kept it securely attached. I have had many a light fly off my saddle bag, but this one stayed on even on bumpy country lanes.

Fixing the light back onto the seatpost mount is easy: it just slides on and clicks into place and isn't coming out until you release the tab.

Another useful feature is that the light can be tilted on the mount, for fixing to a TT bike, for example, or any bike that doesn't have a normal seatpost and you have to mount the light at an angle. The mount tilts via a toolless bolt, clicking to four tilt positions. A good little detail from NiteRider.

Thirty quid for an 80-lumen rear light is pretty good value – if you think you need 80... If you don't, there are cheaper options out there, including the Moon Alcor reviewed recently by Neil; it's only 15 lumens, has a long battery life and is just £15.99. Niterider itself offers various alternatives, and for a tenner more there's the 70-lumen Lezyne Micro Drive to consider.

Overall I'd say the Sabre 80 is a good little rear light, with a sturdy mount offering the flexibility of seatpost and bag mounting. Run-times are decent, with good day and night modes and the added bonus of amber side lights, which are nice to have if not a stand-out feature.
