ORACLE ColorSHIFT DRL upgrade for 2017–2021 Tesla Model 3 includes a BC1 controller option to add Bluetooth control and pattern programming. The ColorSHIFT circuit board replaces the factory DRL board without headlight disassembly and remains compatible with the vehicle system so fault codes are avoided. Use the app to select colors, patterns and white mode for legal on-road DRL operation. Professional installation recommended; white and amber are street-legal.
