A DIY universal type for all cars or trucks. It’s a product for sticking or fastening below the car license plate without damaging to the structure.
When the environmental sunray is lower than 30 LUX, the parking warning light will be turned on.
The parking warning light can effectively warn other drivers to reduce accidents in dark environment or in the nighttime.
When driving during daytime, the parking warning light will not be turned on because the solar panel detects sunray over 30 LUX.  Even driving in the nighttime, the license plate’s side-light will offer 30 LUX ray.
The parking warning light will recharge power from wireless solar panel so it is unnecessary to consume power from car.
