This chart from "Auto Mechanics Center" visualizes the correct usage of vehicle lighting. Understanding these symbols is crucial for visibility and road etiquette. Here is the breakdown:
1. Parking Lights (Sidelights)
The top row shows the symbol with two small outward-facing semicircles.
Function: These are low-intensity lights intended to make the vehicle visible to others when parked or during twilight. They are not bright enough to illuminate the road for driving.
2. Fog Lights
The second row features a lamp symbol with diagonal beams crossed by a wavy vertical line.
Function: Designed to cut through fog, rain, or snow. The beam is wide and aimed low toward the ground to prevent the light from reflecting off the moisture in the air and blinding the driver (glareback).
3. Low Beam (Dipped Headlights)
The third row displays the standard driving light, indicated by beams pointing diagonally downward.
Function: This is the default setting for night driving, especially in urban areas or when traffic is present. The beam pattern is engineered to illuminate the road surface without blinding oncoming drivers.
4. High Beam (Main Beam)
The bottom row shows the most powerful setting, with beams pointing straight ahead horizontally.
Function: Provides maximum long-range visibility on unlit highways. Safety Rule: You must switch back to low beams immediately when approaching another vehicle or driving behind one to avoid dazzle.
