If your car has dimmed headlights, they typically illuminate objects about 100 to 150 feet ahead, depending on the specific design and brightness of the headlights. This reduced visibility can significantly affect your ability to see and react to obstacles, particularly at higher speeds or in low-light conditions. It's important to ensure your headlights are functioning properly and to use additional caution when driving at night or in poor visibility. If the dimming is due to a malfunction, it’s advisable to have them inspected and repaired.

However, it’s important to use high beams responsibly and switch to low beams when approaching other vehicles to avoid blinding other drivers.
