: What do you think about what lights on when? I sometimes like to drive with just the parking and fogs on, added visibility I figure. At times on highways I like to have all on even during daylight as I've noticed this tends to alert SOME slow, left lane hogs (Americans are baaaaaaad in that department:). What do you do?

When I had my E28 (before DRL's) I wired it so the (BMW) fogs were on with the ignition (but still under control of the switch).
Thus I used them as DRL's, and yes they stayed on with the low beams.

However a few years ago there was an "extended discussion" on one of the BMW message boards about this issue. It caused me to take a good look at the issue from the point of the driver approaching a car that has it's fog's on.

I now realise that the fogs often provide glare to the other drivers - much more so than normal low beam headlights.
They are down low, and reflect off the road up ointo the eyes of oncoming drivers - especially bad when roads are wet.

It seems that so many people now use the fogs all the time they have the headlights on, that others now think it is what you are supposed to do.

Perhaps it is time to get an industry standard that when the fogs go on, it turns off all the other headlights - which is usually how I use my fogs in the fog (except that turning off the headlights now brings my high beam DRL's back on - at least they are dim, but it would be better with them off - I guess I need to do another mod)

So now I choose to save any excess voltage for my stereo amp, and only use the fogs with it is "like foggy".

Two exceptions
- on dark narrow country roads, with very narrow shoulders, it helps to have the extra side light to see objects or animals.
- when roads are covered with deep snow the fogs help you better see the depth and position of traffic ruts.

In fairness - I do have the benefit of DRL's - so I can understand why some others would choose to use their fogs "in daylight hours" for the same purpose. While the fogs do not provide the proper DRL projection, they do make the car more visible and that is a good thing.
