At road.cc 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.
What the road.cc scores meanGood scores are more common than bad, because fortunately good products are more common than bad.

For 2018, Exposure's Blaze DayBright rear light has had a few tweaks, resulting in this MK2 version. Thankfully, the excellent output levels, superb burn-times and robust durability still remain, so if you are willing to splash out 90 quid on a light then this should be on your list.
- Pros: Excellent brightness levels, easy to set up for the conditions
- Cons: It ain't cheap...
When I was cycle commuting 200 miles a week whatever the weather, lights were something I was happy to invest in. If you are riding in the dark both ends of the working day, at rush hour, on one of the busiest A-roads in Wiltshire, then not only do you need lights to make you stand out, you need them to be reliable. This is where I see lamps like the Exposure Blaze justifying their price tag.

For starters, its liquid ingress rating is IPX6, which means it has to pass testing where it is subjected to powerful water jets from any direction.
Gone is the top cover of the MK1, which encased the charge port and button, replaced by a black rubber cap like that used on Exposure's front lights.
On two wet rides which killed the IPX4-rated NiteRider Omega 300 (review to come), the Blaze shrugged everything off and no water got past the cover at all. Exposure has placed the charge port on the top of the light rather than on the bottom, which also shows good design sense, unlike many other light makers out there.
Output & battery life
The Blaze offers three programmes, each with a pulse and a steady state mode within them, which keeps things really simple.
Program 1 is the brightest with an output of 80 lumen, which Exposure calls DayBright mode. It's bright enough to be seen on even the sunniest of days from a fair distance, but by no way overly extreme for use in the dark in my opinion.
The pulse mode is definitely eye-catching, with the bright LED flashing once and then a double pulse while a low power output keeps the red glow on permanently.
Early morning rides can often see fog being an issue, but it'll cut through that too.
Battery life is good for a light of this size and power, with the 80 lumen solid mode giving you more than the claimed 6hrs – I achieved 6hrs 28mins – and the pulse giving you 12hrs.
You can see what is happening to the battery life by the colour of the button. It's green when the juice is above 50%, then amber until 25%, before turning red until battery life drops to 5%. If it flashes you haven't got much time left, but the light will switch to the lowest power output to eke out the last of the power.
Charging takes 4hrs from a 500 mA power supply so it's easy to top up at work provided you remember to take the cable with you. Most Exposure lights use a specific cable rather than Micro USB, for example.
Dropping to Program 2 drops the power output by 50% and doubles the burn-time, the same from Program 2 to 3. Flashing in this lowest mode is about 20 lumen, and will give you 48hrs of illumination.
Mounting bracket
The clamp is a simple push fit around the recessed part of the Blaze, which might make you a little nervous on rough roads but fear not! I've using these clamps for years and never lost a light yet. The plastic bracket has a very firm hold on the light and the rubber band is a solid piece of kit.
It will only fit round seatposts, though, so if you have an aero model you'll need to buy the specific clamp from Exposure.
Build quality
Durability is another place where the Blaze justifies its price for me. I've had one of the original Blaze lights from when they first came out probably five or six years ago. It's been used extensively and is still working fine and holding those burn-times. It's been dropped and seen plenty of rain and even snow plus loads of freezing temperatures.
The overall design of this new MK2 Daybright version is pretty much identical, so I see no issues here either. You also get a two-year warranty.

I think the build quality and output make it good value, but you can buy cheaper: Blackburn has both its Dayblazer 125 and the less bright 65 lumen option. Priced at £44.99 and £27.99 respectively, they are quite a bit cheaper than the Blaze.
There is also the excellent Oxford UltraTorch, which costs just £17.99.
I stand by my initial thoughts, though: if you want a bright, reliable light for many years to come, the Blaze MK2 DayBright is worth the investment.
Verdict
Impressive outputs and burn-times make this durable light a great longterm investment

About the tester
Age: 40
I usually ride: This month's test bike My best bike is: B'Twin Ultra CF draped in the latest bling test components
I've been riding for: Over 20 years I ride: Every day I would class myself as: Expert
I regularly do the following types of riding: time trialling, commuting, club rides, sportives, fixed/singlespeed
Since writing his first bike review for road.cc back in early 2009 senior product reviewer Stu has tested more than a thousand pieces of kit, and hundreds of bikes.
With an HND in mechanical engineering and previous roles as a CNC programmer/machinist, draughtsman and development engineer (working in new product design) Stu understands what it takes to bring a product to market. A mix of that knowledge combined with his love of road and gravel cycling puts him in the ideal position to put the latest kit through its paces.
He first made the switch to road cycling in 1999, primarily for fitness, but it didn’t take long for his competitive side to take over which led to around ten years as a time triallist and some pretty decent results. These days though riding is more about escapism, keeping the weight off and just enjoying the fact that he gets to ride the latest technology as part of his day job.

Well, this comments section got a bit weird.
I'd like to see our enlightened friend get his teeth ino a serious issue (helmets would be a good start, or undertaking horses), one wonders what levels of animation we'd have the pleasure of witnessing.
I know my gear and trust it . Im not the one justifying my purchace by calling other people names like you are .
you no your gear.. Really !! All the gear no idea !!
And there was me worrying about tensions between China and the USA over the disputed Paracel Islands as being a potential flashpoint leading to WW3.
I always wondered if you could like your own posts. Now I know.
Tomm Jones. Pls. Stop calling people name to help you justify your purchase of a shit light.
ha ha .. And what amazing super bright rear light do you use then you silly little man. I hope it's better than this amazing light in this review .. If my lights shit then I can't begin to imagine what yours is ...
Surely the mug is the one who's spunked money on any light to be used during the fucking day.
you ain't got a clue little boy.. All the gear no idea I bet ... No common sense .. Ain't got a clue have you ... I love winding twats like you up .. Go on little man .. Reply to this ... You know you want to.. Or are you to busy looking for a decent rear light ..
ha ha luv it well done you clever little boy.. Mummy can buy you a new bike light for xmas now.. I knew you'd reply .. Told you so didn't I .. Luv winding gullible people up ... Ps .. You haven't said what amazing rear light you own.. Come on little boy don't be shy
Hey Tom, isn't it about time you finished your Fortnite game before mummy calls you downstairs saying tea's ready?
Oooh, somebody needs to be igonored!
oh no not another silly person with a tiny little bike light.. There's no hope now !! It's about time someone threw some light on this subject ,, ha ha get it .. Shine some light .
Are you feeling ok?
If there is a need for an 850 Lumens light in daytime, then the problem to be solved is not one involving a light as the solution.
of course there's a need for a 850 lumens light .. On a sunny day on a main road with cars travelling past doing 40 mph and more .. better to be safe than sorry .. It's called common sense .. Unfortunately you haven't got any .. You ain't got a clue with your poxy little light that you think is oh so bright..
To all these people who think this is a bright rear light.. If only you all did some proper research and realised what a useless this little light is.. D.S 500 rear light .. Minimum level 110 lumens!! Max level 850 lumens ..
Yep. I've done my research. I have a 70 lumen back light, and a 50 lumen back light. Both of them are bright enough that they can be seen hundreds of metres away in full daylight, and are bright enough to hurt the eyes of whoever might be riding behind me at night. Just because you have a brighter rear light doesn't mean these arent bright. And what are you trying to achieve with a 850 lumen rear light? That's simply a hazard to other road users. And it's not available any more.
850 lumens is for daytime use only .. You silly person you have no idea.. Do you honestly think car drivers will see your tiny little lights in broad daylight with so many other distractions.. In bright sunlight.. As for night riding it still produces 110 lumens .. You have no idea tbh ... How many other people have said to you how bright your lights are in daylight .. Not one I bet .. Bit different than me then ..
you’re 12 aren’t you?
There is no need for an 850 lumen rear light. Red light is not the same as white light, a 50 lumen rear light has the same brightness as a 200 lumen front light, this is to do with how the human eye reacts to different light colours.
So your 850 lumens is like running a 3400 lumen front light, no one rides along burning 3400 lumens into the eyeballs of fellow road users becuase its downright dangerous and causes people to be dazzled, and yes they might have seen you briefly before being blinded and now can't see anything.
Well done of on your purchase, but you really should re-think running 850 lumens, 110 lumens is a hell of alot for a rear light, read 440 lumens which is way more than is needed to be seen, infact its enough to see with if your going backwards. I good 400 lumen front light (Hope R2) is enough for me most of the time riding unlit country lanes.
850 lumens is only used on a clear bright sunny day on busy roads.. I never ride at night therefore it's never an issue.. The lights got 12 settings ranging from 850 down to 110 lumens .. 6 flash modes 6 steady / flash modes.. I've yet to encounter any one Motoris/ cyclist / pedestrian that says the lights to bright.. In fact I've lost count of the number of times I've had motorist say to me how effective the bright mode is.. As for being damnright dangerous you adjust the power output to suit the situation ..
the lowest it goes is 110 lumens? That’s crazy. I really hate it when I’m traveling home at night and have some cretin with a blinding rear light scorching my retinas. 40 is more than ample in any urban environment. Please never use this light when cycling with others or at night.
+1 for Exposure build quality and customer service.
I've got a Tracer, the brake light function on it is superb.
I’ve had 2 of the Mk 1’s in the past - excellent lights in my opinion. The best for riding in poor visibility or in the dark.
The current Mk 2 version has 2 extra functions not mentioned in the review...
1 - a ‘Brake’ function. When you brake it glows brighter.
2 - a ‘Peleton’ function. When riding in a group. If you have someone begind you the Blaze dims the output. When you don’t it glows bright.
The instruction says they can’t be used at the same time. I haven’t tried these yet, but they sound interesting!!
Now it’s winter I ride with this on the back of the bike all the time, a Strada at 1500 lumens sits on the front. Both use the new flash pattern which is good in that it lasts all day.
Hi Keith57,
Those functions are on the ReAKT version which costs an extra £20 which is why they aren't mentioned in this review.

Buy nice or buy twice..
I've had the Blaze for a few years now.
Well, well worth the cash.
Buy right; buy once.
Yeah, same here and completely echo what you said.
