Tail lights illuminated all the time?
OK, I searched but didn't find this question. Today I left my car running and in park as I ran to grab a newspaper. On the way out, I noticed that the tail lights appeared to be illuminated. (I leave the light switch in 'auto' mode all the time, and it was a bright, sunny morning.) So, I got home and checked various combinations of lights on and off but in no scenario with the car running and in park did the tail lights go out. Brake lights worked as they should, so it's just the tail lights in question. Is that normal? Do the tail lights 'go out' during daylight hours when the tranny is shifted into Drive? I have a 2012 135i BTW...

When your headlight switch is left in "auto" your lights will come on when its dark outside. They will also come on when your wipers are on, and also when you pass thru a tunnel or parking garage. Sometimes once they come on... if its cloudy... the lights will stay on - even though its fairly sunny outside.
IF your headlights come on... so do your tail lights! That is what I think happened. Something triggered your headlights to come on, and hence your tail lights also were on. Did you leave your car engine running? Btw... when ever the headlights come on on the "auto" position... there is a tiny green led that comes on as well on the headlight switch/dial. |

Dackel, that was my first thought. I walked around and looked at the headlights, and they weren't on, just the angel eyes only. When I got home, I checked it again out in the open (not in the garage) and it is bright and sunny (and hot) in Florida today. Still no headlights but those tail light 'tubes' were illuminated. maybe I'll ask the wife to drive away (kind of a risk) and see if they go off.
So I just pulled into the garage, the auto lights came on as usual. I turned the switch to off, so the headlights go out, but the tailights stayed on. Turned the car off, tail lights go out. Last edited by TX135i; 06-03-2012 at 11:10 AM.. |

If you have selected your DRL's (angel eyes) to be operational then the rear lights (light tubes) will also be on. If you de-select your DRL's to be on then the rear lights will be off. Hope this help.

It's the DRL's (daytime running lights). The angel eyes and the taillights are a part of this. You can turn off the DRL's if you wish, but visability is the reason for them.

Yep, that's what it was. So help me out, this BMW thing is new to me....So you can only have the angel eyes on via the DRL selection, and if you do that, that means the tail lights are on too, correct? There's no way for angel eyes with no tail lights?
It just seems like I see BMWs all the time with angel eyes on but I don't recall seeing tail lights on during the day. My wife's Acura, her previous Lexus, and even my old Honda Civic had DRLs that come on up front but no tail lights. |

If you select DRL, then the AE's and LED tail lights are on by default. If you deselect DRL's then they are off. When the headlights are on because of ambient light or your wipers are on, the AE's are also on along with the tail lights.

Older BMWs only used to use the angel eyes or headlights for DRL (depending on country regulations and specific model), but since about the 2008 model year, new BMWs use both the headlights/angel eyes and tailights for DRL. Not so with my 135. DRLs are "on" via the dash/computer selection (non-iDrive), but no part of the tails are illuminated. I have LUX AE's installed...not sure if that has anything to do with it.

Wait, I don't get this. Even when my light switch is in the completely off position, the tail lights are still on. Even in broad daylight. This is confusing...

you guys just want to be able to turn off all lights at night to evade the cops!
In my young and reckless years I blew past a cop taking radar on the HW at night I just blasted up to the next off ramp with the lights off and eased the hand brake to make a stealthy exit

If your car is a Canadian one or coded as such, the DRLs can't be switched off and the taillights will be on.

Earlier 1-series cars (U.S.) only used the front lights (AEs for HID lights and high beams for halogen lights). At some point, BMW started using the tail lights as DRLs, too. Not just the 1-series, either, this was pretty much across the board. Perhaps now they reverted back to the front-only lights as DRLs. All I know is that my car only uses the front lights as DRLs. I also know that you can code the car to remove the rear lights when the DRLs are on.
