Why Is the Fog Lamp Darker Than the Headlamp

The function of the front fog lamps is not to illuminate, but to provide a high brightness scattering light source. The intensity of this light source is to penetrate the dense fog and remind the driver on the opposite side. Although it can light up a small area, if used under normal conditions, it is enough to dazzle the eyes on the opposite side.

 

In this case, it is immoral to turn on the front fog lamp. It is recommended not to use it under normal circumstances, but only in dense fog. Even in heavy rain, you only need low beam headlights, and fog lights will not give you any help.

Why is the fog lamp of the motorcycle darker than the headlamp?

 

Do not use the rear fog lamp under normal conditions. Because the brightness of the rear fog lamp and the brake lamp is the same, both are 21W. The tail light is 5W.

 

The light of the brake lamp is scattered light, and part of the light of the rear fog lamp is directional light. For the driver directly behind, the rear fog lamp is brighter than the 5W+21W dual filament brake lamp. In this case, the rear fog lamp will only lead to rear end collision.

 

The design specification of the low beam lamp must provide sufficient illumination for the road. However, the beam direction must be strictly controlled, for example, the main beam has a 1.2% slope. The purpose of anti dazzle is to rely on this slope. This makes the light only shine on the ground, not the eyes of others.

 

The design specification of the front fog lamp is not used for lighting purposes. It provides a powerful scattering light source in extreme weather conditions (the visibility is less than 20M). This allows the relative moving vehicle to find each other.

 

Of course, this light source is too strong and dazzling if it is not filtered by thick fog. Therefore, the front fog lamp can only be used - the visibility is less than 20M high beam lamp.

 

In cities, the high beam should not be used for more than one second. On the expressway, if there is no vehicle ahead, please use high beam lights. But if you become a member of the team, you should certainly not use high beam to shine on others. When driving on the expressway, if there are no cars behind, you can consider the rear fog lights, which can help some vehicles that are speeding beyond the speed limit to find them early.

 

The rain can't block much light, so the low beam light is enough. The front and rear fog lamps shall be turned on only in case of heavy rain and 20M visibility.

 

Conclusion

 

The high beam lamp shall be used as little as possible. As long as necessary, the front and rear fog lamps shall be turned on. If conditions permit, the low beam lamp shall not be used as much as possible.
