Magicshine SeeMee 200



Innovative and generally likeable light, but brake function needs revision
Clever dual lens
Frugal daylight flash
Good run times for the output
Brake light is too sensitive...
...and that affects run times

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.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

The Magicshine SeeMee 200 is a very potent and eye-catching rear light with a neat cube design. The 200 lumen claim is a bit sneaky – that's with the brake light activated – but even so, it's a winner with some very practical settings and good run times. Unfortunately, to get those run times you have to switch the brake light function off...

There's a fair bit of technology packed into this little composite cube, and it's all well sealed from the elements with an impressive IPX6 rating, meaning it can resist heavy rain and pressurised water (but not submersion so avoid, you know, harbours and river beds and stuff).

Look closely and you notice not one but two lenses: a main light and another beneath, which Magicshine calls the 'tracing light'. This projects a 360-degree arc of red light down to the road. It's not a not a new concept, but probably the most effective version I've come across.

The main lens casts a 260-degree arc, which should avoid stealth moments when turning. The large main Cree LED is flanked by an outer wall of tiny diodes.

Though not quite bewildering, there are eight settings and it's a good idea to sit and digest them before heading off for the first time. Broadly, though, the modes are divided into steady, flashing, and smart.

There are three steady: high (140 lumens), mid (70 lumens) and low (30 lumens). Next you get four flashing modes: Breathe, Comet, Flash and Interactive. All are 140 lumens, and run different sequences and tempos.

Last but not least is the smart setting, where an ambient light sensor adjusts intensity between 140 and just 10 lumens for maximum efficiency. It also switches off the trace light during daylight.

There's a useful, automatic power kick down when the battery reaches five percent (which it will surprisingly quickly if you're running the brake light function). From there you've got around 20 minutes before the system shuts down.

The battery indicator is functional, if crude. Green denotes anywhere between 100 and 20 percent, whereupon it turns red – there's no amber. Get really low and the red starts flashing.


The lithium polymer cell refuels from the ubiquitous micro USB cable, and a full charge (on mains power) takes two hours. Bargain on another 20 minutes or so from a laptop. Much like everyone else's, the indicator switches from red to solid green when fully juiced. The charge port cover is a reassuringly snug fit, and I haven't felt the need to add silicone grease.

The mounts

The SeeMee 200 uses a sturdy rubberised 'watch strap' which has entertained the full zodiac of post diameters and, crucially, much thinner things like seat stays too (I've even successfully mounted ours to helmets). There's also a saddle rail mount for a really sleek fit.

The switch

This is a simple, top mounted rubberised affair. It's fairly positive, and requires a two second press to power up and a double click to switch modes – the likelihood of unwanted changes is pretty remote. It's easy in gloves, and the unit remembers your last mode and restarts there, which is good.


Magicshine claims it's visible to 3,000m. I can't honestly attest to that – that's nearly two miles – but it is genuinely very bright, even on the brightest days. Friends reckon they can pick me out from half a mile or so, and even chainstay mounted, that tracing light puts you in the spotlight.

I haven't honestly dared push the SeeMee 200 to its theoretical 50hr maximum burn, but I've crept past thirty with no issues and – given how accurate the run times are in the heavier modes (within a few minutes over 3-4 hours), it seems likely to be trustworthy.

Brake light

Add the 200 lumen braking function to its 140L steady mode, though, and the run time drops hugely. First time round, I was surprised to see the fuel light turn red after 90 minutes, though it managed another 70 minutes before kicking down to the 30 lumen flash and switching off the tracer lamp.

True to the claims, I got another 20 minutes before it completely shut down.

That incredibly bright (and power-sapping) brake light seems a little too sensitive, and it's easily triggered by small lumps or even swerves to avoid debris, as well as by actual braking.

It feels effective, though. On deserted lanes, cars and vans generally seemed to chart more cautious overtakes.

The 70 lumen steady setting is arguably the best at night, while the low 30 lumens seems good, as opposed to painfully harsh, for group rides or stop-go traffic. Interactive offers the best nocturnal burn time at around 4hrs 30m.


There are a lot of lights at around £34, but few with this spec, which makes direct comparisons tricky. The Tern Vizzy rear light is another quirky design with a tracer lamp, but despite some nice touches it can't hold a proverbial candle to the SeeMee 200. It's a fair bit pricier at £44 too.

For less power but arguably better performance on long-distance commutes or winter training rides, Magicshine's own SeeMee 100 (review to come) is only £25.99 and also features a brake light.


The Magicshine SeeMee 200 is well made and has some neat, intelligent features for the money. While the brake light is oversensitive and drains the battery pretty hard, this is still a very usable, effective, and bright light for all kinds of riding.


Innovative and generally likeable light, but brake function needs revision test report

Make and model: Magicshine SeeMee 200

Size tested: 200 Lumens

Tell us what the light is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Magicshine says: "Most powerful model in the Seemee bike tail light series, the Seemee 200 has a super bright main light and a secondary area light, providing optimal visibility for urban and road cyclists."

It's a clever and bright light with sensible modes, but the braking function is too sensitive and hurts run times.

Tell us some more about the technical aspects of the light?

* 200 lumens max main light, 140 lumens consistent, 260 degrees wide visibility from behind the rider, visible from more than 2 miles away

* 360 degrees visibility secondary area light, forming a circle of light under the rider

* Brake Sensor: 200 lumen brake light that lasts 3 seconds(heavy on battery usage, press and hold power switch for 5 seconds to turn this feature on/off)

* Ambient Light Sensor: Auto adjusts light mode and output depending on ambient light conditions(only in smart mode)

* Low power mode: Power saving flash mode triggered automatically at 5% battery and lasts 20 min

* Memory function: Saves the last mode used when the the light was turned off

* 3 brightness modes and 4 flash modes(double press to change modes, single press to cycle options)

* 2.5 – 50 hours runtime depending on mode

* 40 g in weight

* USB rechargeable(battery non-replaceable)

* Seat post mount and saddle rail mount

* IPX6 Waterproof

Rate the light for quality of construction:

Solidly made and well sealed from the elements.

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

Very user-friendly, but read the instructions carefully.

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

Simple but versatile and reliable.

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

Very well sealed. Resists heavy rain and waterlogged roads without missing a beat.

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

Good, provided you disengage the brake function, which is a recurrent theme across this family of lights.

Rate the light for performance:

Phenomenal output and presence, but mode choice and braking function can put a big dent in run times.

Rate the light for durability:

Solidly made, so no reason to believe it shouldn't live a long and productive life.

Rate the light for weight:

53g doesn't present an issue for me, and it's very solidly made.

Rate the light for value:

Impressive given the performance and specification.

Tell us how the light performed overall when used for its designed purpose

It's very impressive.

Tell us what you particularly liked about the light

Solidly made, nice spread of modes and the trailer light.

Tell us what you particularly disliked about the light

Overly sensitive braking function.

How does the price compare to that of similar products in the market, including ones recently tested on

Very favourably. There are a lot of lights at this price point, but few with this spec – which makes direct comparisons quite tricky. The Tern Vizzy is another quirky design with a tracer-type light, but despite some nice touches, it can't hold the proverbial candle to the SeeMee 200 and is a fair bit pricier too.

Did you enjoy using the light? Yes

Would you consider buying the light? Yes

Would you recommend the light to a friend? Yes

Use this box to explain your overall score

This is an innovative, well made light with sensible modes that cover most bases well. If the braking function wasn't so oversensitive it could be an eight – a reliable brake light and decent run times would be great – but as it is it's good and a seven.

Overall rating: 7/10

Shame no photo taken from behind the bike in the dark, to see how effective the light shone at the ground is.

Who buys this kind of overpriced light, full of thechnology that you don't need ?

For the same money (or less)  buy 2 basic lights and set one on continuous, the other on flashing.

Keep safe.

Hirsute replied to nortonp | 3 years ago

Depends how much lumens you require. If you need day light, low sun defensive measures, then at 140 lumens that is quite useful.

Plus it only weighs 40g and it has good wide visibility which not all have.

It is a fantastic rear long as you don't use the brake light function....which really is not needed as the light is bright enough as it is.... I tend to use either one of the "day flash" modes (can't remember it's magic shine name) or the Auto mode which switches the rear and lower led's as per the ambient light....and if stationary turns off to save battery..... other than the brake light it's brilliant, compact and good for the money....

But suffers from the common flaw of rear lights, the insistance that they can only be fitted below the saddle. And so not viable to shorter riders using a tools and tubes saddle bag, or any rider with a larger saddle bag for a commute or touring.

How about more seat stay brackets for these lights?

Ah, I just skimmed the technical data "* Seat post mount and saddle rail mount". and looked at the photo. It will end up pointing at the sky somewhat, but the review does state

"Friends reckon they can pick me out from half a mile or so, and even chainstay mounted, that tracing light puts you in the spotlight."

I assume they mean seatstay, as chainstay would have it pointing vertically up (or down), and it would be hidden within the bike rear triangle. I'll be tempted to give it a go, if I don't resolve my exposure traceR mounting issues.

I'd hope they would provide some sort of spacer but old inner tube or a shaped wine cork would do if sjscycles don't come up with something.

TheBillder replied to Hirsute | 3 years ago

Ah, the full zodiac from Aquarius to Sagittarius plus Ford and some rubber boats. Russell Grant your guide.

I must say I've never bothered about the brake light idea or the auto brightness even though my Moon Arcturus has the latter. Just a nice bright lamp on the bike (with very bright for daylight use) and a strong blinker on the helmet, as when driving I find them hard to miss and instantly know there's a bike ahead.
