Using Fog Lights

So you already have your headlights on and your tail lights are working just fine. Do you really need some fog lights on? Actually, the answer to this is: it depends. Fog lights may seem like it’s the same as your head lights but really, it’s not. For one, fog lights are yellow in color unlike head lights which are usually clear and tail lights which are known to be red.

There’s actually a scientific reason why fog lights are colored as such. When lights hit vapor, they need to be in a different color so that you can still see through. If it’s white, then it might just mirror the water vapor contained in a foggy environment and therefore still not let you see the road clearly ahead. Some experts say that red would have been a good choice too but because it’s already associated with stop and brake lights, yellow is the next best option.

So when should you attach fog lights? If you live in a place where there’s humidity and the temperature often drops, you will definitely fog lights. This also applies to places which often experience rainfall. Most SUV’s or big family wagons come equipped with fog lights in preparation for long trips wherein you may likely come across humid air conditions. Fog light often make use of halogen lights as they emit such powerful wavelengths.

Halogen also enables fog lights to have a tighter beam than that of incandescent ones. But at present, new experiments on fog lights shows that some mineral compounds can actually make up this product. But as a result, they would light out the way in purple rather than the traditional yellow fog lights.
