They combine high-density 2835 SMD chips with a full-view optical lens and aircraft-grade aluminum housing to increase visibility while maintaining long life and stable operation. Non-polarity design makes installation straightforward, and the built-in CAN-BUS circuitry reduces the chance of dashboard errors or hyper-flashing on most vehicles.\u003c\/p\u003e\n\n\u003ch3\u003eHow much brighter is this LED compared with my factory bulb?\u003c\/h3\u003e\n\u003cp\u003eThese SEALIGHT LEDs use multiple 2835 SMD diodes and an optimized lens to concentrate light where it matters, producing a significantly stronger and whiter output than standard halogen filaments. The result is improved rear illumination for safer reversing in low light or adverse weather.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eAbout 700% brighter than typical stock 921 halogen bulbs.\u003c\/li\u003e\n  \u003cli\u003e6500K cool white color temperature for high contrast and clarity.\u003c\/li\u003e\n  \u003cli\u003e360° emission with lens-driven light utilization for wider coverage.\u003c\/li\u003e\n  \u003cli\u003eIdeal for backup, reverse, and third brake lamp applications.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these bulbs trigger an error or hyper-flash on my vehicle?\u003c\/h3\u003e\n\u003cp\u003eSEALIGHT integrated a CAN-BUS ready circuit to minimize error messages and flash-rate issues on most modern vehicles.
