It's fair to say we love the Magicshine SEEMEE300; this incredible rear light has had many highlighted deals, and for good reason, it's pretty much all you could ask for in a rear bike light.
It may have been superseded by its more costly and brighter SEEMEE400 sibling, but Amazon Prime Day is here, and once again, the four-day shopping extravaganza has brought another outstanding deal on one of the best rear bike lights we've ever tested.
Right now you can get the Magicshine SEEMEE300 for just $41.99, not quite the lowest it's ever been, but we won't quibble over the $2 difference; it's still a bargain buy.
And talking of cycling deals, our Prime Day 2026 Live ticker is the place to find all the best deals as we find them.
With a whopping 200 hours the SEEMEE300 ha the best battery life of any rear light on the market. Even the SEEMEE400 can't match it at 107 hours of runtime, it does have extra lumens to power, so it makes sense that it would struggle to keep up with the 300.
SEEMEE300 is also super bright with two rear facing LEDs that have a maximum 300-lumen output, and you guessed it the 400 has... 400-lumen of output. The unique feature of both is the downward-facing LED light, and its a game changing highlight, and illuminates a large cone of light below you and gives 360 degrees of effective visibility.
The list of smart features it has in its arsenal include auto-dim which dims the light to suit the ambient lighting conditions and prolongs the battery life, and the motion sensor acts as a brake light, something that is really useful if you're a regular commuter riding in traffic.
This Amazon Prime Day deal makes the Magicshine SEEMEE300 incredibly good value for money, when compared to the SEEMEE400, and we reckon it's an absolute steal.
