1. Premium Material: The door lights are made of high-quality, flame-retardant ABS. Their robust housing is waterproof, shockproof, and corrosion-resistant. The new grid-based heat dissipation design makes the product resistant to high temperatures and pressure, while effectively protecting the lens and integrated circuit of the welcome lights. Heat generated during use is thus dissipated, extending the product's lifespan. 2. High-Definition Projection and Vibrant Colors: The light passes through a high-definition insulating film. Thanks to the Ultra HD multi-layer lens, color differences are effectively reduced, faithfully reproducing the original HD colors. Once lit, the door lights transform the appearance of your car. 3. Advanced Decoding Technology: Our products include the latest embedded decoding chips, ensuring full compatibility with your car's software and existing circuit modules. High-quality components and circuit boards fit your car perfectly and enhance its comfort without unwanted electrical current noise. 4. Easy Installation: The welcome lights are plug-and-play! No drilling, no wiring, no disassembly, and no damage to your car. 5. Efficient Heat Dissipation: The heat dissipation system uses professional superconducting aluminum heat sinks, low-power chips, bright LED lights, and stable components to ensure high temperature resistance and efficient heat dissipation. You don't have to worry about your door lights stopping working due to overheating. 1546 Impeccable After-Sales Service: If you encounter any quality problems or are not satisfied after receiving your order, please contact us.
