First come, first served! #Aya's Item List 【Door Opening Warning Function】 When the car door is opened, the LED lamp set attached to the door automatically lights up, and the highly visible orange signal flashes alternately, warning cars, bicycles, motorcycles, and pedestrians behind the car door, helping to prevent danger when getting in and out of the car and preventing rear-end collisions. It automatically turns off when the car door is closed. 【Benefits of this product】 1: Genuine product with quality assurance. 2: Lights and flashes on both the side and back of the car door, visible from multiple angles behind the door. 3: The lamp is only 6.7mm thick, and the circular magnet chip is only 2mm thick, making it thinner and usable without interfering with most car doors. 4: Carefully designed packaging to match the product quality. I think it would be very good as a gift. 【Lamp & Power Supply】 The color of the LED lamp band is red when not lit, but it turns orange-yellow when lit and flashing alternately. If the door is left open for about 50 seconds, the warning lamp will automatically turn off. Powered by built-in button batteries, the button batteries can be used for about 6-7 months under normal use. Easy to replace button batteries. 【Installation】 No wiring required, easy to install, with Japanese installation instructions. 【Product Set & Quality Assurance】 2 LED lamp bands, 2 circular magnet chips, and 1 of this product can be equipped on two car doors.
