Fog lights
How do you like the fog lights, do they work well? When I look at the X1 relative to other cars I've had with fogs they seem to be kind of high, and in NorCal I actually do find good fog lamps useful. Has anyone replaced the bulbs yet?
Also would love to see any pics of them at night. |

I think I'm changing mine to yellow later on down the road....

Higher lights are actually better IMO, especially if they're white. Lights closer to the ground often concentrate most of their lumens(illumination) 10'-20' infront of the car, far too close to be useful when driving actually, but the lowered fog lights are a look that's popular. Color matters more for actual vision in fog than any height would.

They are not meant to illuminate more than a few feet in front of the vehicle. They're meant for pea soup conditions, not light haze. They light up areas very close to your car, so you can find the road while driving slowly. Yellow lights do this better, by providing a higher contrast and less reflection. If they go farther than 20', you have a big problem, in that you will illuminate the cloud of fog in front of you, and see even less in the conditions fog lights are meant for. |

Didn't misunderstand... But it's all opinion and preference. First, white fog lights are pretty much worthless IMO. Most manufacturers do fog lights at all for style, not function. I hope BMW did the height for functionality and not style but since they're white I'm already questioning function. But anyway...
In my experience, fog lights under about 18" off the ground typically will focus most of their lumens 2'-10' in front of the car and are wasted as the driver can't see that close due to the hood or it's not useful at more than 5mph and in if it's that bad you shouldn't be driving. Due to DOT requirements of downward lighting angle and avoiding fog lights causing problems for oncomnig traffic you can only illuminate further down the road by increasing the height of the light. My preference for fog lights are most lumens focused about 20'-40' ahead, still allowing you to see at 1mph in the worst of fog to get off the road but in mild fog at 20mph. |
