Final answer:
Motorcycle headlights must typically be on at all times for safety, known as the Daytime Running Lights law, though local laws vary. The claim of being blinded by a rising moon is unlikely, as its brightness is insubstantial compared to vehicle headlights. Automotive headlights are designed with mirrors to concentrate light into a directional beam for better night-time visibility.
Step-by-step explanation:
The statement that the headlights of a motorcycle must be on at all times during operation is generally true. This safety requirement is known as the Daytime Running Lights (DRL) law in many jurisdictions. Its purpose is to increase visibility of the vehicle during the day to prevent accidents. However, specific laws may vary by local jurisdiction, so it's important to check the laws in your area.
Concerning the claim about being blinded by the Moon during a car accident, while the full moon is indeed bright, it is unlikely that it could cause temporary blindness when rising on the horizon. The brightness of the moon is not comparable to the intense glare of headlights or the sun, which can cause such an effect.
Figures 25.46 and 25.47 describe how the light from a bulb is trapped by two mirrors to create a directional beam, similar to how automotive headlights work. The mirrors focus the light into a narrow beam, providing a way to illuminate the road ahead effectively during night-time operation.
