This newly upgraded automotive welcome light features a one-piece transparent housing design with geometric diamond-shaped patterns, perfectly embodying minimalist tech aesthetics. The black circular reflector concentrates the powerful LED light source, ensuring a clear and sharp projection pattern without light scattering. It is compatible with BMW 1/2/3/4/5/6/7 Series models, as well as the X1/X2/X3/X4/X5/X6/X7/M/Z/GT series. We pay attention to every detail, using high-quality flame-retardant wiring, a stable power module, and a durable waterproof housing—all components undergo rigorous testing to ensure long-term reliability. Installation is simple: just mount the light at the bottom of the door and connect the power to activate the smart switch function—the lights turn on automatically when the door opens and off when it closes, saving energy and giving you peace of mind. This welcome light is not only ideal for daily commutes, family outings, and business receptions, but also a creative choice for car clubs, wedding processions, and brand promotion events. It transforms every door opening into an anticipated moment, inviting passengers to embark on a journey filled with a sense of ceremony.
