Does any of you guys know if the DRL--LED turns on at night too? I swear I saw an E350 sedan with both headlights and LEDs on one night. I have an E350 coupe. I tried this on both auto and manual light mode but no luck. Yes, I have enable DRL on the settings already. Is this some sort of re-programming that has to be done through star diagnosis? Any takers? Thanks.

In Canada,where running lights are compulsory,they are reduced to 10% power when the head lights are deployed.

Found this from Konigstiger:

Have your dealer check VMI to see if VIN is included in this campaign if so the dealer will perform work.

The LED's on my car are on when the headlights are on but are much dimmer than during the day.

Whats a W207? The new E-coupe is a C207.

I guess so, I saw S350 today and it had LED running on at night. However E350 which I drove didn't have LED. Perhaps it is an option.

The LED is a P2 option in the U.S. for the 2010 E-class. The brightness is reduced for both sedan (glow at 10%) and coupe (glow at 50%) in the dark.

Sorry...i know this is an old thread, but....

Under the Convenience feature, I enabled everything under the Lighting menu. My DRL LED (hockey stick) turns ON during the day. At night, everything (HIDs, inner projectors, side markers, and DRL LED) turns ON. My light switch is at "O".

I notice that with those settings mentioned above, and I turn my light switch to "A", the DRL LED turns ON during the day, but it turns OFF at night...only the HIDs, inner projectors, and side markers turn ON.

Hope this helps.

I have a 2012 E350 Coupe with P2 Package.

Yes, when my headlights are turned-ON at night, the DRL LEDs will also remain ON (but dimmed from the daytime brightness -- I guess Mercedes does not want them to blind the drivers of the cars ahead.)

(I cannot confirm this, yet I have heard from some C207 owners that without the P2 package, the DRL LEDs will not remain ON when the headlights are turned-ON... Can any other owners confirm this? Thanks.)

My E class coupe 2011 model the hockey lights turn off automatically when head lights turn on. I also saw other cars in the road same model as mine and the head lights and running lights are both on. Is there any special programming with STAR program for that. Does somebody knows how. I called MB dealer but they don't have idea. They replied that day lights must be off at night but I want them on.

Holy zombie thread!

The DRLs should be ON with the head lights but with much lower intensity. They are full power at daytime when head lights are OFF.

Thanks Arrie for your prompt reply. What you describe is what I wanted my car do but unfortunately as soon as the headlights turn on the day lights turn of immediately . I imported the car from UK and as I read on some forums there is a rule in the UK low that not allow the day lights running on night. So my question is : does the running lights can be programmed with a computer to run on night or I must change a hardware or something else . Our dealer here in Cyprus has no idea . My model is E220 Blue Efficiency cdi AMG a and year of first registration is 11/2011

Arrie

I'm not sure but somehow I remember that the DRL has two set points for intensity. One is 100% at daytime and then the lights take the dimmed set point when head lights come on. I remember reading somewhere that this dimmed set point is 30% and that set point is adjustable thru the Star system.


If it operates like this it could be that this dimmed set point in your car is just set to 0% meaning no light at all when head lights are on. Could be as simple as just changing this 0% to something else to make the lights burn with the head lights.


But as I said I'm not sure of this. Just remembering reading about this somewhere.
