Headlamps and wipers

In just noticed that turning on the windshield wipers does not automatically turn on the headlamps when the automatic headlamps setting is selected. I would have thought it would. New Jersey has a law that if your wipers are on, you must have your headlamps on too. The halos are on of course, I wonder if those will count when I drive by the cops?

But even so, from a safety point of view, I would have thought BMW would have set the wipers being on to turn on the headlamps. Headlamps on in the rain is always a good idea. Rain generally means reduced visibility. They are so into safety in other areas, but not in the case?

Running lights are on. I was just trying to point out that headlamps are probably better in the rain than running lights. My suggestion to BMW is that if your lights are in the auto setting the the car puts on full headlamps with wiper activation rather staying with the running lights.


I just mounted my summer tires. I am waiting for them to break in so I can then put the car's handling though its paces and then i'll report back. I immediately noticed a huge difference (improvement) going to the GFT Michelin PSS from the factory RFT P7 A/S. Sneak preview- I love this car! Best I've ever had, except maybe for my 1970 Mach 1...

With the auto wipers on, the car will automatically turn on the lights once the wipers start going and reach a certain speed of wiping.

Yes, it tested this out, the lights do indeed come on in most cases. They do not come on automatically when using the rain sensor.

Turn on wipers with rain sensor - running lights only lit, headlamps do not come on.
Turn on wipers manually by pressing lever up once (or twice), headlamps turn on.
If you go back to rain sensor mode after running wipers in manual mode, headlamps stay on.

So it seems to work mostly as I thought it should, but you have to remember to run wipers in manual mode, initially at least, to get lights. I don't understand why rain sensor alone doesn't also turn them on, maybe BMW is trying to conserve energy.

What Mo said. The auto wipers will turn on the headlights when they determine the rain is heavy enough to need them.

I checked the Owner's Manual to see if this function is described in detail. Unless I missed it, I could not find any details on this subject. Is this function described in the Owner's Manual?

It is a legal requirement in some US states. You may not have the requirement in ZA.

It's not mentioned in the manual. But the car does indeed turn on the headlamps with wiper operation, except in cases of very slow intermittent wiper operation.
