My mirrors have only one inch clearance through our garage door, so I need high precision when I park. Current version AP2 Summon always parks too crooked for all four doors to be usable, so I built a tool to help me park perfectly every time: More images These runway lights are placed to be perfectly vertical in the rear cam if the vehicle is aligned properly. Now I can precisely park right where I want it on the first try. The lights are a rope of individually addressable WS2812Bs in a water tight casing. The vehicles can track a lot of water into the garage, so I designed and 3D printed 30 little lifting rails to allow drainage. The light cycle is controlled by a simple program on an Adruino Pro Mini and power is switched on whenever the garage door is open. I used a blob of clear silicone caulk every foot or so to secure it to the floor. Happy to answer any questions if anyone else wants to geek up their garage like this.
