Odd DRL questions

A few questions as I haven't taken delivery of my new GC yet to look at.

I notice some WK2's seem do have different DRL behavior and I am wondering if some of this is programmable or maybe just different by model or year. These questions only pertain to the WK2's without LED DRL (so like the standard Limited model headlights)

Here are the different things I have seen:
  • No daytime running lamps at all
  • DRL is the innermost (I think high beams) bulbs and are on all the time
  • DRL is the innermost and when a blinker is on that side light turns off
  • DRL is the outermost (projector lens) I think thats the low beam and is barely lit

So what I am trying to figure out is if the DRL functionality is programmable as far as which lights it uses, turned off completely and so on.

From what I have observed...

Depends on the model year and the headlight option.

First gen WK2 models (2011-2013) with halogen lights had no standard DRL, but it can be turned on by the dealer and then it uses the high beam halogen bulbs with partial voltage (dim).
First gen WK2 models with HID lights used the HIDs as low/high and then the 'high beam' area had a 3157 bulb lit up as DRLs standard.
Both of them turn off the DRL when the turn signal is used since the high beam reflector is in close proximity to the turn signal for enhanced viewing of the turn signal during the day.

From what I've noticed with second gen WK2 models (2014+)...

If you have the standard halogen headlights, the low beam is used as a DRL standard from the factory.
If you have the LED/HID headlights, then the LED surround is used as the DRL.
I haven't seen the turn signal in a halogen headlight equipped model as I have only seen them heading the other direction on the freeways around the Twin Cities.
The LED/HID headlights turn off the white LEDs when the amber turn signal LEDs are on/flashing. Again this is to enhance the visibility of the turn signal during the day.

Re: Odd DRL questions

Is there a way to turn off the DRL on the Overland/Summit? I see some driving around without theirs on and I have never found an option to turn them off... Not that I want to. Just curious.

They can be turned off through settings in UConnect.

This should clarify things for you :

2011-2013 WK2 (halogen) {low beam DRL} require dealer intervention to activate or deactivate
2011-2013 WK2 (bixenon) 3157 bulb DRL (DRL bulb can be removed if DRL is not desired)

2014 and up halogen and (selectable in u connect)

Actually...
2011-13 WK2 halogen headlights use the HIGH beam bulb as the DRL.
Dealer can activate, but as one who had them activated I highly discourage doing so.

I had them disable again.
Running the high beams at low voltage results in brown deposits forming inside of the bulb, thereby dimming the light output when you actually use them as high beams.

I'll be replacing my 9005 bulbs next month now that I've had the dealer turn off the DRLs.

My personal experience was the low beams were activated by the dealer. And all the 2011- 2013 I have seen with del were the Low beam. Info also confirmed by literature on WK2Jeeps.com - 2011-2016 Jeep Grand Cherokee.

If you pay attention to the headlights you will notice the WK2 with quad head lights only illuminate the highness when you use the flash to pass.

That is because the low beams are used as DRL.
