A very bright optional LED brake light. If you are worried that your car may be inadvertently driven into from behind, this brake light will help to indicate your actions clearly on the road. 180 bright LEDs sealed in silicone produce 28 watts of power. The brake light works from both 12V and 24V, so it is completely universal. Thanks to adhesive tape it is glued under the glass of any car. The length of the glowing tape is 35.4 inches.
