Because the light is un-switch before
sometimes it pass through objects
It may be static electricity, or more possibly... an ungrounded light switch.
Non-luminous refers to objects or substances that do not produce light on their own. These objects rely on an external light source to be visible, as they do not emit their own light. An example of a non-luminous object is a table.
Because light can't directly reach the objects, or reflect well off the inside walls of the box. So not enough light bounces off the walls, then bounces off the objects, and then goes to your eyes.
Check your headlight switch. Sometimes the switch goes bad and the dash lights won't light. Replace the switch for the fix.
Brake Lights "Stuck" ONUsually that is caused by the brake light switch becoming "out of adjustment," but sometimes it can be caused by a defective brake light switch.

transparent and translucent objects are the objects that let the light pass through them eg glass, but sometimes translucent objects are colorful so they change the color of the light as it passes through them opaque objects can either absorb the light, like dark material, or reflect, like a mirror.
The issue with the light not consistently turning on when the switch is touched could be due to a faulty light switch, loose wiring, or a poor connection in the circuit. It may also indicate intermittent electrical contact within the switch itself or a problem with the light fixture or bulb. To resolve this, it's advisable to check the connections and replace the switch if necessary. If the problem persists, consulting a licensed electrician is recommended for safety.
If by "light" you mean electromagnetic radiation, then you would call them energy radiators.
try replacing the dimmer switch they sometimes go bad and do not allow voltage to the lights
When the eye is unable to focus light effectively, it can lead to conditions such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These conditions result in blurred vision and difficulty seeing objects clearly at certain distances.
