Xiaomi 4 Pro owners - if your rear light's acting up or broken, this replacement is your perfect fix! IMPORTANT: This ONLY works with Xiaomi 4 Pro models - not compatible with mi4, mi4 Lite, mi4 Ultra, or mi4 GO, so double-check your scooter model before ordering. Made from durable ABS material that's both lightweight and weatherproof, this tail light is built to last. The bright LED illumination seriously improves your visibility and safety, whether you're riding at night or in rainy conditions. Installation is straightforward - the 40cm cable gives you plenty of length to work with, and it just plugs right into the taillight position. You get everything you need in the package: 1 rear light, 1 fixed buckle, and 2 mounting screws. The waterproof and dustproof design means you don't have to worry about the elements damaging your light. At 5.9x4.2cm, it's the exact same size as your original light, so it fits perfectly into the mudguard. No special tools or technical skills needed - if you can use basic screws, you can install this. It's an affordable way to keep your scooter safe and legal without paying for expensive repairs. Seriously, if your current light is dim, cracked, or just not working, this replacement will have you riding safely again in no time!
