Final answer:
The two colors allowed for vehicle front lights without special permission are white and amber, selected for visibility and differentiation, ensuring road safety.
Step-by-step explanation:
The only two colors allowed for lights in the front of a vehicle without special permission are white and amber (yellowish-orange). These colors are designed to ensure vehicles are visible and recognizable from a distance, which is crucial for road safety. Headlights on your car are typically white, providing maximum visibility for the driver, while the color amber is often used for turn signals and running lights, which are easier to differentiate from headlights, helping to convey the appropriate signal to other road users.
