1. Understand the Purpose: Rear foglamps are used to increase visibility for vehicles behind you in low-visibility conditions such as fog, heavy rain, or snow. They are much brighter than regular tail lights and can help prevent accidents in adverse weather.
2. Use Appropriately: Ensure that the rear foglamps are used only in appropriate conditions to avoid dazzling drivers behind you. If the weather improves and visibility increases, turn off the rear foglamps to prevent causing unnecessary glare.
3. Check Manual Control: If the warning light indicates that the rear foglamps are on, check the foglamp switch to confirm they have been activated intentionally. If not needed, turn them off to conserve battery power and prevent misuse.
4. Monitor Conditions: Continuously monitor the road and weather conditions. If visibility becomes clear, turn off the rear foglamps to avoid distracting or blinding other drivers.

Proper use of rear foglamps enhances safety during poor visibility conditions, ensuring you are visible to other road users without causing unnecessary glare.
