Magicshine has recently released a number of new Seemee taillights that combine smart features with impressive output. In this review, we’ll be looking specifically at the Magicshine Seemee 180, one of the higher output variations that has a unique LED design. The Seemee 180 is well priced at $39.99 for the features, and also boasts a maximum of 180 lumens of output. With this latest generation of tail lights, Magicshine has incorporated both an ambient light sensor as well as a brake sensor. These two sensors allow the taillight to automatically adjust the output based on the current conditions as well activate a boosted output mode during deceleration to attract attention. 

The Magicshine Seemee 180 is a bright tail light with unique optics and integrated sensors to keep you visible at night.

The Seemee 180 comes in a simple box with the characteristic black and orange graphics. Another nice feature is the large opening in the center of the packaging that allows you to interact with the tail light.

In the box you’ll find:

  • Seemee 180 tail light
  • Seatpost mount
  • Saddle mount
  • 2x Zip ties
  • Micro USB charging cable
  • User manual
  • Warranty card


The Seemee 180 comes with two mounts out of the box: a seat post mount and a saddle rail mount. While the seatpost mount has the same design as most mounts, a plastic mount with flexible rubber strap, Magicshine has added a clever design detail. The rubber padding has the standard round cutouts for round seatpost mounts, as well as a second smaller round cutout at the center. Tiis second cutout allows the seatpost mount to also work on aero seat posts that have sharper trailing edges which would cause typical seat posts mounts to not sit flush. With a simple second cutout, Magicshine has created an easy to use seatpost mount that should work with nearly any seatpost.

In addition to the seatpost mount, a simple plastic seat rail mount is included right out of the box. It is a single sided piece of plastic that has two rounded hooks that snap onto your saddle rails (note elliptical saddle rails will not work). On our saddles, the saddle rail mount had a satisfying click when installed and felt secure. We prefer the higher mounting of the tail light as it has a cleaner look on the bike and better visibility. However, if you are using a saddlebag or high-mounted fender you may not be able to utilize this mount. We do wish Magicshine had included a body clip as it would’ve been convenient to mount the light to a saddle bag or backpack.

The Magicshine Seemee 180 has a tall rectangular profile with a unique lens design that utilizes transparent optical fibers. There is a two part illumination pattern with a uniform outer ring plus an eye catching inner portion that is horizontal on the upper portion and vertical on the bottom. The Magicshine logo is ghosted onto the left and right sides of the housing. With the light off, the lens is not visible from side angles, which initially had us worried about side visibility. However, part of the housing surrounding the lens of the Seemee 180 is transparent and becomes illuminated when the light is on allowing for 260° visibility.

On the back of the light is a simple quarter turn style mount (a feature shared with the other Seemee tail lights), and a micro USB port under a rubber cover. The light is rated for IPX6 which means wet weather riding should not be a problem. Although we wish the battery was replaceable (like the Lupine Rotlicht), the integrated battery provides great runtime and allows for a better sealed tail light.

The user interface on the Seemee 180 is well designed, as it utilizes a single click to change the setting within a mode or a double click to switch between output types (steady – flash – smart). A long press turns the light on or off in any mode with the built-in mode memory ensuring the tail light is always restored back to the last selected mode. Magicshine has also incorporated a battery status checker into the one-button interface (quite similar to the Fenix BC05R and BC21R v2 lights) that allows you to short press on the power button to illuminate the backlight for 3 seconds to indicate the battery status. It is a three-level indicator that turns either a green (21-100%), steady red (6-20) or flashing red (>5%). This is a feature we’re excited to see, as it lets you check the battery before you start riding.


The Magicshine Seemee 180 has an integrated motion sensor that can automatically detect braking to activate the boosted 180 lumen mode. Regardless of the current output mode, the light will switch to steady 180 lumen for a few seconds to attract attention. This is a feature that’s becoming increasingly popular and can provide extra safety on the road. How effective is it? That isn’t clear, especially as there is no standardized implementation but the light output change should draw attention. One downside with the brake sensor feature though is that runtime becomes reduced depending on how often the mode is triggered.

The calibration of the brake sensor is an additional aspect that determines how useful the feature is. With the Seemee 180, we found that it was overly sensitive and would trigger even on bumps. This is consistent with the Magicshine Seemee 60 which also had a sensitive brake sensor and would often trigger when riding. We prefer the calibration of the Fabric Lumasense V2, which was less sensitive but still not foolproof. Although Magicshine doesn’t provide multiple sensitivity options like the Lupine Rotlicht, you can toggle the brake sensor on/off by simply holding the power button while the light is off for a few seconds. Additionally, the Seemee 180 will revert to a standby off mode if no motion is detected after 1 minute to conserve battery.


Not only did Magicshine integrate a brake sensor into the Seemee 180, they also added an ambient light sensor. Unlike the Seemee 200 which also uses the sensor to determine if the downward facing LED should be activated, with the Seemee 180 the sensor is only used for the smart output mode. If the sensor detects higher ambient light, the smart mode has a slower on-off flash output (better suited for daytime riding). In low-light situations, the output mode switches to a low power/high power flash setting to improve nighttime visibility. We preferred to ride with the smart mode as it allows the Seemee 180 to automatically choose the best mode for the conditions. This provides a similar experience as the Light and Motion Vya Pro or Bontrager Flare RT and is one of our favorite features.

COMPARISON (Seemee 180 vs. other Seemee tail lights)

If you’ve made it this far into the review, you may be wondering how the Magicshine Seemee 180 compares to the other Seemee tail lights. Across all the current Seemee tail lights (200/180/100/30) you’ll find the same light output modes, user interface, battery status checker and ambient light sensor. The Seemee 180 is quite similar to the Seemee 100 in terms of form factor, but uses a more unique optic design for only a $5 higher retail price. The Seemee 200 has the highest output of the Seemee tail lights, with the 200 lumen boosted braking mode and unique downward facing LED that lights up the road. Although we prefer the dual LED design over the Seemee 200, the Seemee 180 has a larger rearward facing lens and slightly sleeker profile. For us it’s a bit of a toss up between the Seeme 180 and 200 as they are nearly the same price and have slight advantages over each other. 


More is better. At least that’s the strategy Magicshine uses when they develop the output modes for their lights. Across the Seemee tail lights (200/180/100/30), Magicshine has programmed three constant modes, four flash modes and the slick ‘smart’ mode for a total of 8 settings. A single click cycles through the different levels and a double click to alternate between the main steady – flash – smart setting groups. Unlike the Seemee 200 which uses the ambient light sensor to control the secondary tracer LED, the Seemee 180 only utilizes the ambient light sensor for the smart output mode.

The three steady modes are: low (27 lm), medium (63 lm) and high (125 lm) with runtimes that vary from 1.5 hrs to 3.5 hrs. Instead of only having the typical on/off flash, Magicshine has added four different flash patterns: breathe (ramps up from 0 lm to 125 lm and back to 0 lm), comet (ramps down from 125-0 lm), flash (standard on/off at 125 lm) and finally interactive (alternatively flashes the inner and outer rings at 125 lm). The runtimes for flash modes vary from 2.5 to 6 hours, and we particularly like the breath and interactive modes for their uniqueness. The last mode is called ‘smart’ and as we discussed in the previous section utilizes the ambient light sensor to switch between 125 lumen flash or a 9-125 lm night mode flash. 

Although the flash modes are distinct from each other, the smart mode is quite similar to the flash and interactive mode which makes it easy to get lost while cycling through the different modes. We would prefer if Magicshine simplified the number of output modes to ‘smart’ and perhaps a steady or flash mode though, something Light and Motion Vya Pro has done. In real-world riding, there is little use to having so many modes, particularly when a light sensor can be programmed to automatically optimize the output for the conditions. Also, if you plan to do multi-hour rides, you’ll need to remember to use the flash, interactive or smart mode to ensure you have enough battery runtime.


Overall, we found that the Magicshine Seemee 180 is a smart tail light that ensures you remain visible from all directions. The integrated brake and motion sensors provide automatic features that are useful in real world riding while the partially transparent housing ensures you have 260° visibility. Even though we wish the brake sensor calibration was better tuned, Magicshine has provided an easy interface to disable the brake sensor if desired. We are also very happy to see the three level battery status indicator that lets you easily check the battery status instead of only relying on a low battery warning. Although the Seemee 180 lacks the secondary tracer LED of the Seemee 200, we found that it is a very well priced tail light with unique optics that set it apart.
