Cadillac Fog Light
Fog lights are usually used to provide extra low level illumination, helping you cut through heavy fogs, snow and rain. For this purpose, Cadillac fog lights are not that bright compared to other lights in your car. The headlights when used in fog will just reflect the light back to you, forming a white haze in front your car, rendering them futile. You need your fog lights to give you light to drive by; furthermore, you need them to keep your car visible on the road.
Cadillac fog lights unlike other fog lamps are integrated with DRLs (daytime running lamps). They light up as long as the engine is running, but you can also set them on or off as you wish. When your headlights are off, you can use your DRLs and fog lights for more visibility, especially in the morning when the sun is just about to rise and in the afternoon when it is about to set.
