Magene L308 Review 🚴🏻♂️🔦💡 An intelligent expression tail light
Magene asked me to help publicise its new tail light. The thought of flashing emojis under my saddle didn’t especially appeal to me. I guess I’m not the target market. However, the company is very persistent and they have some nice products coming out in 2024 so I thought I’d play nice in 2023.
It got worse for my ego, rather than the 5 minutes I’d anticipated spending on it I ended up playing with it for well over an hour! Maybe it’s not so bad after all 😉

⭐⭐⭐⭐ Perfect if you want customised flashing and scrolling emojis on your bike's tail light.
Summary
A great little light that’s a bit of fun and bright at the same time. Is it just for kids? Not sure.
Pros
- bright
- fun
- customisable lights
- easily attached
Cons
- somewhat childish
OK, it’s not in the same league of smartness as the Magene L508 smart radar tail light
Installation
It has a good generic mount that fastens to your bike with thick rubber bands and the mount has a Garmin-like quarter-turn fitting for the light. It can be easily attached and detached.
You easily pair the app with the OnelapFIT app to set up the customised LED light patterns. Here are some images from the app to give you an idea of how it works
In Use
At 30lm it is bright and that should make you noticeable for half a mile.
It’s also lightweight and sufficiently waterproof, and I got 10 hours of battery life from it, although the specs say you can get up to 50 hours presumably if you have fewer active LEDs in your light pattern.
Special Features
Other than custom emojis (the product’s key, niche feature) the light will turn off when not in use and, handily, you can customise the inactive period before it turns off. Also, the smart braking sensor presumably works with the light’s onboard accelerometer, detecting your rapid braking and enabling 3 seconds of rapid flashing as an alert to vehicles. Less handy for group riding.

In Action – Magene L308 Intelligent Expression Tail Light
Note the light pattern is much more readable in real conditions. For some reason, I couldn’t video it properly and the light appears blurred.

There is a mistake in your description. When braking the light doesn’t light up solid. It flashes few times instead. This is very annoying and not legal in some countries.
ty, great spot. change made
