This may be a stupid question but how do can you tell if your headlights are on when in auto light mode. I always have my lights set to auto mode but cannot easily tell if they are on or not especially when it is cloudy and raining. I have checked a few times when i thought they would be on as it was so overcast and wet and they weren't so put them on manually. I thought there should be some indication on the dashboard display that they are on but have not seen anything. How dark does it have to get before they come on?

The standard green colour light (the same as when you put the lights on manually) lights up on the dashboard everytime lights are activated automatically. Vadim A.

The RRS auto lights are one of the last ones on the road to light up, look for reflections on the car infront of you that usually lets you know if they are on or not

And in my case the last ones to turn off when exiting a tunnel into bright sunshine. FF 4.4 V8 Soooo looking forward to this bad boy
Ex 2006 RRS SC - garbage
Ex 2016 135i M Sport - dream car
Ex 2003 RS6 Avant - piece of cr*p
Ex 2014 320d X Drive, M Sport Touring - ok I guess
Ex 2007 RRS TDV8 - bloody loved it
EX 2007 FL2 XS - not so bad

I will have to check when i get home as I am sure that no green light comes on when the lights are actually on. In the right light I can see that the dials light up but mostly its quite difficult to tell if they have or not.
I have resorted to looking at the car in front to see if there are refelctions but thats not always possible to do.

There is a little dial just below the light switch, have you tried adjusting that? It allows you to brighten or dim the instrument lights

You can also see where you are going, especially at night  In Spain - 2018 F Pace - Frightened away from the Sports due to crank failures
Gone - A couple of RRS, A couple of Disco's. However thinking of another Sport.

green dash light appeared in 2007

My 2005 D3 didn't have one, the only way (apart from facing a wall/building) was to flick the lights onto manual and see if the dash dimmed.

My 2007 RRS has the light RRS gone

Thank you for the replies. I am indeed in a 55 model but thought I was going mad as I could see no indication that lights were on ....because there was no indication. Agree though that is somewhat easier to tell in the dark!
