Turb Signal Bulb Lites w/o Key?

Odd little happenstance yesterday. I was at work when someone called over
the intercom and said there was a red BMW in the parking lot with it's
lights on. There are two of us with red cars. So, rather than walk the,
seemingly, 10 miles to my car, I did the easy thing and checked to make sure
I had my keys. Yep, got 'em. Can't be my car, right?

Well, while on my usual walk at break time, I strolled by my 330 and lo and
behold, the driver's side turn signal light was lit. Front and rear. I said,
"wtf?" Got in and everything seemed normal. Main switch in usual position,
no key in ignition and again I said, "wtf?"

Well, turns out as I was exiting the car I must have pressed down on the
turn signal stalk with my lunch pail and not noticed. Unbeknownst to me, the
bulbs are energized and stay lit even with all switches in the off position
and no key in the ignition. They don't flash, they just stay lit. Works on
both sides, front and rear, by the way.

Is this normal? An electronic glitch specific to my car? Have others noticed
this with their cars? What possible reason would BMW have made this a
"normal" occurrence?

Any and all replies will be appreciated.  :-)

This is normal, and required of cars in Europe.  It's not against FMVR,
so they just leave it that way.  VW, Porsche and others are just the same
(not sure about SAAB or VW...)

Didn't realize it, but ditto for both my cars (U.S. '99 E46 & '03 Z4).  Will
be on guard in the future!

You don't have to be. It will happily run those lights overnight.

Yeah. Doesn't seem to be a big current draw but why is this "feature" there?
Because BMW doesn't want to defeat it on US cars? Seems silly.

No, it seems sillier for them to spend $$$ to remove it, when
US regulations don't require them to.

Could be useful if you had to park on an unlit road? It's not easy to
accidentally switch it on, though.

In that context I agree. Also, since the current draw is so minimal and
there is really no chance to drain the battery, unless of course you were to
leave the car unattended for days or weeks I guess, I see why the "feature"
was not removed or defeated for the US models.

It's not a requirement in the UK either, but I often use it when parking
the car on the street away from home.

Some years ago I had an Audi that had the same facility.
Means you can just switch on the offside front and rear parking lights, to
reduce power consumption when parking on a road at night.

Correct operation.  All four of my BMW's have done this, as do most EU cars
(Merc, Audi, Volkwagen, even GM & Fords IIRC).

Great if you have to park somewhere dark or a bit awkward at night, and want
some charge in the battery to start in the morning.
Dan Krueger - 10 Sep 2005 22:16 GMT
I just went out to the garage and both my '04 X5 and '02 330i do the
same thing.  The key doesn't have to be in the ignition.

It's not the 'turn' signals which are on but the 'parking' lights. And you
must have operated the turn signal control after stopping the engine and
switching off.

My 1972 2002tii touring euro-version does this, but I'm pretty sure the US
version cars I've had don't.
