【Waterproof and Dustproof Material】Our LED car coasters are made of acrylic, which has a waterproof and dustproof surface. This material protects the cup holder from spills, stains, and wear, while ensuring the surface is easy to clean and durable. Acrylic is also a robust material, increasing the coaster's durability and allowing you to use it for a long time.

【Light and Vibration Sensor】This LED coaster features a built-in sensitive light sensor and a vibration sensor. When the light is low or the car body vibrates, the coaster automatically illuminates, making it easier to find the cup holder. If there is sufficient ambient light or no vibration, it automatically turns off after approximately 15 seconds, saving energy. 【Easy to Charge】This LED light-up coaster recharges via a USB port. Its USB port makes it easy to recharge for many occasions. It takes 2 hours to fully charge and can be used in the car for approximately 15 days after a full charge. It's an essential accessory for long journeys. 【7 Colors and 3 Modes】The button on the back of the light can be pressed to change the color or mode of the light-up coaster.
