Setup, Compatibility & Care
Installation of the Bullvision D1S/R bulbs follows a simple plug-and-play procedure: remove your existing D1S or D1R bulb, disconnect the power cable, and snap the new LED bulb into the factory socket. No external wiring harnesses or ballasts are typically required. To maintain peak performance, ensure that the cooling fan intake remains unobstructed by dust or debris. It is recommended to perform a standard headlight aim adjustment after installation to ensure the output remains within legal requirements and does not cause glare for other drivers.
