Three Gesture Modes: This gesture light features three gesture modes that can help alert other drivers and attract their attention, or friendly drivers to express your love or gratitude. Of course, the driver takes a bird out on the road to do some annoying things. Bright enough day and night: composed of 176 LED beads. Gesture car devices are bright and clear enough that you can use them during the day and night to ensure other drivers can clearly see the gesture lights. This is a cool car gadget for drivers. Powered by three AA batteries (not included), lasts approximately 6-7 months, with a standby time of 8.2 months (0.44mA). Easy to install: Just peel off the tape on the gesture light and remote control, stick it where you want and stick it for 30 seconds (please clean the area you want to stick beforehand). Then you can start showing interesting gestures.
