Because your engine is too hot.
or the light is broken.
The speed of light does not have a temperature.
The relationship between temperature and light is that temperature affects the color and intensity of light. Light itself does not have a temperature because temperature is a measure of the average kinetic energy of particles in a substance, while light is a form of electromagnetic radiation.
Neither visible light nor ultraviolet light have high temperature, because temperature is associated with molecular movement and light is an electromagnetic wave or particle having no temperature. Infrared light is given off by matter that is raised to high temperature, but that is not the same as having temperature.
the temperature of a IR light is 6500 degrees fahrenheit
the temperature of a UV light is 10nm-400 degrees fahrenheit
How does the angle of light affect the temperature of a surface?
Light does not have a temperature because it is a form of energy, not matter. However, the temperature of the source of light, such as the sun or a light bulb, can affect the surrounding environment. For example, a hotter light source can increase the temperature of a room, while a cooler light source may have a lesser impact on the environment.
Cold light
The oil temperature light usually means that the temperature of the oil has reached a dangerous point. The oil temperature light will alert the operator to turn off the engine.
engine coolant
For the temperature: thermometer.For the light: luxmeter.Moisture: hygrometer.Wind: anemometer.
When matter absorbs light, the energy from the light is transferred to the particles in the matter, causing them to move faster and increase in temperature.
