Disable daytime running lights?

[cxha]

Nope, because I drive with the parking lights on until headlights become necessary based on the conditions. Parking = Front halos, side markers, and tail lights. There is never a time when there are no lights on my car. And from the sounds of it, this is even safer than people who rely on DRLs that don't turn on the rear lights.

I like that configuration as well, lights visible 360 to me is safer than only the DRLs in front.

Why is no one mentioning that turning off DRL’s also disables the headlight cooling fans.

Hopefully extending their lifespan (and known to fail prematurely due to inferior bearings).

Approx $2000 parts and labor to replace just ONE assembly!

Once the DRL code process is completed, how do you verify DRL’s are off

The process says that after completion, drive over 2 mph to verify process took effect.

Guess you need a car in front of yours to observe?

I'm not following you here. If the lights are turned off, what does it matter if the fans are also off, shouldn't they be?

"I'm not going to use this feature because I don't want the thing to break"...

Headlight cooling fan death isn't so common that you need to turn all this off.
Girl I work with won't use her folding mirrors on her BMW... "I'm afraid they might break." Sooo, turn it off if one breaks then?

I disable the folding mirrors on mine for the same reason (especially freezing in winter), but I normally don't need them folded and I re-enable them if I do need them in tight parking etc.

If I disabled them only after they break, then I wouldn't have them when I needed them

Yes, no DRL’s… no operating cooling fans.

You should be able to tell the difference driving at night, or you can try to see the reflection in some windows.

DRL are part of the headlights assembly, including low beam and high beam lights. If the cooling fans are indeed disabled, that implies that there will be no more cooling for low and high beams.

All the code does is unlock the options on the stalk so it no longer overrides the selection. That's it.

I was guessing, rather. Now, that I am reading about the cooling fan and all the knowledge people here have about the headlights, I am wondering whether I should be the one worrying about a potential low beam failure. I disabled the DRL's by physically removing the DRL relay, not using the recommended method. I've done this two-three years ago and so far I've had no issues butt it still makes me wonder.

Great points!

I don’t know WHERE my brain was at!

 

[7eregrine]

Totally get running folding mirrors only when you need to fold them. But not because they might break. Simply because you can. I rarely NEED mine to fold (on my other car).

Not using a feature, or turning one off because of failure concerns is what I have an issue with. Use your car. Why save these things for the next owner?

This stuff is confusing me on my 2022 Premium Plus.

If you do NOTHING (no stalk/hazard procedure, or no DRL relay removal)….

Then isn’t the car “halos only” if the stalk is in the “parking light” position?

And if so, why make any changes at all?

In other words, I thought if you go through the program sequence, the car would be “halos only” when daylight, and stalk is in “auto” position. Then revert to normal mode st night.

And if I remove the relay, I get “halos only” when stalk is in “parking light” position. Halos plus DRL’s in auto mode.

But I get that with the relay installed as well.

What am I missing?

Only until you start moving. Automatic headlights engage over a few mph, not based on a light sensor.

Damn… sorry! I still don’t get it,

If your at daytime highway speed, where should the stalk be to have halos only?

Once you do the unlock code, you'd use the parking light option.

The way Mazda designed it is like this: no matter the position of the light stalk, the DRL lights turns on after the car starts moving. Some people like it, some don't.

Thanks guys.

Think I got it now.

I was hoping for an automatic day/night switchover: daytime: Halos only. nighttime: halos with normal headlights.

I guess that isn’t in the cards.

Begs another question tho:

Without doing the code, what does the parking position on the stalk do?

I’m assuming nothing (acts like full on non automatic).

So the only purpose the parking stalk position serves is IF you complete the code and want halo only)?

 

[N7turbo]

Without doing the code, what does the parking position on the stalk do?

When the car is not moving, it works as expected. All parking lights and the halos are on.

When the car starts moving, the headlights come on, and what other lights are on depend on the stalk position. According to others, the tail lights don't automatically come on in Auto mode, and you need to flip to the headlight option to turn them on. That doesn't sound like good design to me; even 20-30 year old cars had automatic headlights based on a light sensor (my Pontiacs did).

Given that, doing the stalk unlock procedure is the best of all worlds. You get control to drive with the halos on and headlights off during the day or at times when you don't want to shine bright lights, and you can't accidentally drive without tail lights because you'll have to turn on your headlights manually anyway.
