Disabling the Auto Headlight Function

That's it, I'm done flashing my lights twice to turn them off at night. I think I'm old enough to turn on and off my own lights.

How do I disable these auto lights? Is there a wire I need to cut? A fuse I need to pull? What do I need to do?

Thanks,
M

On the left side of your steering wheel there is a little multi-function arm... the one that does the turn signals. On the end of it is a switch you can turn. It controls the headlights. You can turn them off completely, put them on auto, and turn them on manually from there. The switch for the fogs is also on the the arm, more inwards toward the steering wheel.

Well aren't you just clever.

I'm saying how do I DISABLE THE FUNCTION. I always turn on my own lights, but the issue is that at night, when I twist it to OFF, it passes AUTO on the way and flashes the low-beams a second time before turning off. Which not only looks dumb to bystanders, but is also bad for the bulbs and ballasts. I want it so when the switch goes to AUTO, NOTHING HAPPENS.

i found this to be a problem as well since i was so used to turning on and off my own lights rather than just keeping it on auto. now i just switch to the auto position instead of the on position at night so i wont have to pass through that 2nd flash of lowbeam.

Yep. If auto was before OFF, that would have been perfect. That's how it is in my sister's Dakota.

AUTO / OFF / PARKING / LOW

or

OFF / PARKING / LOW / AUTO

I'd prefer the second, but meh.

I'm sure you could rewire it - if you took the arm apart.

Why?
At night:
On: turn it from Off to Auto
Off: turn it from Auto back to Off

Because I hate auto headlights. That's why. I want control over my headlights.

haha sorry Mazaki... don't get all defensive... i misunderstood your question. I didn't mean to insult your intelligence, but I know some people who really wouldn't know they had a headlight switch.

Now to your real question. Take the arm off and grab a voltmeter. Your gonna have to sit and play with the connector until you figure out which pins are associated with the auto headlight setting of that switch. Then your gonna have to disable them somehow... you can probably just pull them out with a needle nose. Should take care of the problem, but it would be much easier if you have a wiring diagram. I don't think there is any other way to do it.

Just so you know though, the oem headlights are designed to be rapid cycled. So flashing them twice really shouldn't do any damage aside from looking stupid. Did you ever notice that setting off the car alarm flashes the headlights? It really is perfectly harmless. But I agree, it is still a stupid way to design the switch.

But you are contolling them by just using the auto at night. You turn it on and boom they turn on. You turn it off and bom they are off. Just like a big boy. If someone scratched off the work "auto" and replaced it with "on" then you would never know the difference.

I like the auto-headlight feature except for the fact that Infiniti made it way too sensitive; the lights keeps going on and off driving through Southern California maze of freeway underpasses and overpasses; they should have added a 7-10 sec delay to avoid these kind of conditions.

The light sensor is on the passenger side of the windshield air vents. Get some eletrical tape & cover it => no more auto headlight.

From the manual:

The life of xenon headlights will be shortened
by frequent on-off operation. It is generally
desirable not to turn off the headlights
for short intervals (for example, when
the vehicle stops at a traffic signal). Even
when the daytime running lights are active
(Canada only), the xenon headlights do not
turn on. This way the life of the xenon headlights
is not reduced.

Maybe try turning the switch faster? I flip mine from on to off all the time and they never flicker twice even when it goes past auto. I do it fast enough that it just goes straight off.
