The mainstream chassis lights utilize LED light sources due to their high brightness, low energy consumption, and long lifespan. Chassis lights are based on flexible LED light strips, integrating multiple high-brightness LED beads through a flexible circuit board. The number and arrangement of these beads affect the uniformity of light emission. The surface of the light strip is covered with a transparent or frosted silicone layer for waterproofing and dustproofing; some products feature IP67 protection. The circuit board is typically made of high-temperature resistant FR-4 fiberglass board.
Their working principle relies on precise current control by a controller, supporting voice, light, or remote control modes. For example, a built-in microphone can capture ambient sound to change the light according to the rhythm of music. Features include support for various lighting modes such as constant light, strobe, gradient, and breathing. Users can customize color combinations via remote control or a mobile app.
Some products use LED beads with a high color rendering index (CRI>80) and a light guide plate design to ensure soft, non-glaring illumination. The LED chassis lights provide a concentrated illumination area, pointing directly under the vehicle to form a light strip.
