The solenoid controls the high and low beams. Which leads me to the next component of the headlight, which is the solenoid. Without the cutoff shield, you’d get a more round light output shape, similar to a flashlight. You’ll probably recognize this, but here is a shot of the distinct barrier that a cutoff shield produces: The cutoff shield creates a distinct light barrier so that the light coming out of the headlight is concentrated out and down, and keeps the light from exiting out and up, which would blind oncoming traffic. The headlight manufacturers tune the headlights so that you get an exceptional experience. The lens is used to throw the light in a very precise and even manner. If the magnifying glass is held too closely, or too far away, the light spreads and the leaf doesn’t burn. If you line things up just right with the sunlight and a dry leaf, the magnifying glass lens will concentrate the sunlight to a fine point and the leaf will begin to burn and smoke. If you’ve ever been 9 years old, you know that when you take a magnifying glass outside on a sunny day you can have some fun. The distance the light source and reflector are from the lens determine the intensity and dissipation or concentration of the light.Īn easy way to wrap your head around this is to compare this to a handheld magnifying glass. The lens bends, spreads or concentrates the light. It’s a reflective half-sphere that throws the light from the light source in a specific direction.
