How To Fix/Replace a Broken Ninebot Max G30 Tail/Brake Light

January 27th, 2021





While transporting my scooters up to college, the taillight on the back of my max broke off.

This makes me a lot harder to see at night as I have no brake light, so I opted to attempt a fix.

This process takes about ~15 minutes from start to finish and requires some specialty bits.

Disassembly

Once my new tail light arrived from China and I procrastinated fixing it for 6 weeks, it was time to disassemble the scooter.

4 Security Torx T20 screws hold the gray plastic plate in place underneath the rear of the vehicle.
