Door Welcome Lights: Infuse Your Car with a Touch of Elegance! These newly upgraded welcome lights are compatible with BMW 1 Series, 3 Series, 5 Series, 7 Series, X1, X3, X4, X5, and X6 models. Featuring a one-piece transparent housing and a geometric diamond-pattern design, they showcase the beauty of technology within a minimalist aesthetic. The black circular reflector focuses the powerful LED light source, ensuring a clear, glare-free projection that shines brilliantly in the dark. We have paid meticulous attention to every detail. High-quality flame-retardant cables, a stable power module, and a durable, waterproof housing have all undergone rigorous testing to ensure long-term, reliable performance. Installation is simple: just mount the light at the bottom of the door and connect the power supply. The light intelligently turns on when the door opens and automatically turns off when it closes—combining energy efficiency with convenience. Ideal for daily commutes, family outings, business receptions, and more, it’s also an excellent choice for car clubs, wedding processions, and brand promotions. Turn every door opening into a moment to look forward to, ushering in a journey filled with a sense of ceremony for you and your passengers. Package Contents: 4 welcome light units (2 pairs), 4 power cables, 1 installation tool, 1 user manual.
