A simpler version of the MK2 light we liked so much, and at £20 cheaper it's also great value

We tested the Exposure TraceR's fancier stablemate in November and really rated it, and the TraceR MK1 DayBright is a slightly simpler version that's every bit as good but more affordable.

  • Pros: Very bright, lots of modes, good run-time, price
  • Cons: Umm... etched graphics a bit worn already

I won't bore you by repeating everything Dave Arthur said about the MK2. Suffice to say, I don't disagree with any of it. The main difference in the MK1 is the absence of ReAKT technology, which allows the light to adjust intensity automatically, depending on light conditions and braking forces. Since Dave's main dislike of the MK2 was the price, he should be pleased to know the MK1 comes in a full £20 cheaper for leaving out the ReAKT gubbins. And it's 2g lighter for it.

All the other good features are there. Exposure's 'Optimum Mode Selector' technology is boffin-speak for 'three power settings' but what's cool about it is that under each setting you can scroll between just two simple modes (pulse, steady), making it much easier to use from the saddle.

Setting which of the three power levels you want involves pressing and holding the power button until the red light flashes. First flash is high power (more on that in a moment), second flash is medium, and the third is low. Obviously, you need to be able to see what you are doing so this is not an operation to be performed in heavy traffic. However, once selected, it's very easy to find the power button (if you make sure you put the light in the bracket with the button facing upwards) and switch the light on or off, or between modes, just by feel. I even did this with heavy winter gloves on.

The brightest setting is what Exposure calls 'DayBright', and as well as using all the 75 lumens on offer, the flash mode gives a double strobe to really emphasise your presence on the road. It could be a life-saver on winter days with low sun, though you won't win friends by using it in traffic at night.

The looks have proved divisive, judging by people's comments on Dave's review of the MK2. Yes, it does stick out like a sore thumb, but on the plus side, if you ride with a very crowded seatpost area (racks, saddle packs and so on), it's much easier to get it in and out of the bracket than some clip systems that involve sliding the light up or down. Like Dave, I found the bracket simple and secure.

Exposure prides itself on its UK design and build, and spares and servicing are a real thing here instead of the break-it-and-buy-a-new-one approach so prevalent in many areas these days. So, given the lower price ticket over the MK2, I would say this offers excellent value.

Rate the light for quality of construction:

Well made and sealed with a pleasing machined finish and anodised red. The etched graphics were already worn when it came to me.

Rate the light for design and ease of use. How simple was the light to use?

You need to be able to see what you are doing to choose which of the three brightness levels you want. After that, it's easy to switch on and off, or between modes, from the saddle. The button was easy to locate even with gloved hands. Simple to remove for charging, though you do need a USB cable to hand.

Rate the light for the design and usability of the clamping system/s

A very simple bracket, made of tough nylon, into which the light clips. It's held securely and the bracket mounts with a silicone band (the red silicone is a nice touch).

Rate the light for waterproofing. How did it stand up to the elements?

Excellent. A simple silicone ring covers the on/off button and the USB socket. You don't need to remove this for charging so it's unlikely to get lost. Withstood some very wet rides and a couple of hosings.

Rate the light for battery life. How long did it last? How long did it take to recharge?

I got 3 hours 10 minutes on full-power, 2hr 30mins recharge. Exposure says 3hrs run, 4 hrs recharge so actually better than claimed.

Rate the light for performance:

Excellent – bright, easy to switch, good side visibility.

Rate the light for durability:

Should give years of good service – if not, Exposure is easy to contact.

Rate the light for weight:

For the rugged build and durability it's hard to fault this.

Rate the light for value:

Very competitive, given the quality construction, materials, tech support and performance on offer.

I love exposure lights, beautifully well made with great battery life. 

My only gripe is the bright red silicon mounting bands. Not subtle or stylish.
