So I recently upgraded my footwell lights to leds and noticed immediately as mentioned, that they stay on as you drive and they stay lit even if you shut off the car.
They don't use enuff energy to drain your battery, but I did not want they on when the car was off
The oem incandescent bulbs, as mentioned, are also, always on, but not as bright and yet use about 4x the amount of battery juice as the leds.

So for my facelifted r171, this is how I got (good english), the led footwell lights to shut off completely when car is off

there are 2 ways to do it.

1. As mentioned, lock/arm the car. The led footwell lights go off immediately

or if you are like me, I keep my car garaged and do not want to arm/lock it. If I needed something in it, I would have to disarm/unlock the car, meaning I would have to go inside and get the fob, etc.

so the method is

2. After driving car and off and parked, you will notice when out of car, leds in footwells are on and stay on.
a. lock the car. the footwell lights will go off immediately
b. wait until car goes to 'sleep', usually 10 mins. If you have ever sat in your car after shutting it off, you will recognize the sound when it goes to 'sleep'.
b. unlock the car with the fob
c. open the car door (I use the passenger door). The courtesy light and footwell lights come on
d. close the car door. The courtesy light goes off at 10 seconds (if set in menu)
the footwell lights go off completely 30 seconds later (total 40 seconds, same if you unlock car with fob but then do not open any doors, they will relock (in case one accidentally presses unlock button on fob))

Again, this was in my fl R171. If you had leds and did not know they were always on, happy to make you paranoid.

I'm the original owner of an '05 '55, but in 12 years of owning the car never noticed that the footwell lights stay on "forever" if you leave the car unlocked.

Last evening after dark we drove to a spot where we could see some local fireworks while sitting in the car, and after being parked for about 30 minutes noticed the footwell lights still on, but very dim.

After we arrived home, I was able to duplicate the experience, and eventually figured out the footwell lights will fully shut off if the car is locked.

I was however wondering if something was amiss, and a search lead me to this thread.

My car spends a lot of time in the garage unlocked and unused. I recently installed my 4th battery despite that I usually will throw on the battery tender if the car is going to sit for more than several days.

Of course I'm now wondering if this (plus my Piecha roof module, which someone recently mentioned also has a parasitic draw) has contributed to the lousy battery life I've experienced.

Anyone have an idea how many milliamps the footwell lights draw when dim?

And it goes without saying I'm going to start making it a habit to lock my car even when it's in the garage
