Auto Headlights...

[woodsfortysix]

Just returned from a 2400 mile trip in my three month old Genesis with no problems. I did notice early today, while we were driving in a west / north-west direction, that the headlights (and the NAV system) would flip back and forth from night to day mode several times a minute. It was bright and sunny (about 8:30AM), but the sensor was not in the direct sunlight. Later, when the angle of the sun changed, the situation did not occur.

Is this normal? I could not find any sensitivity settings to adjust.

Thanks...

I have noticed the same thing, mostly in winter, and especially late in the afternoon (sun is probably at the same angle as the time in the morning you mentioned), but it was not even close to being dark (maybe 4 PM or so). So yes it is normal, but a little bit annoying. There is no adjustment for it that I have heard about.

I have experienced the same thing. Similar situation as you described. I believe it is normal for the Genesis though it could probably use a little adjustment. I haven't worried about it and it doesn't happen all the time, usually doesn't for me. If it does happen, I just go to manual mode.

Thanks for the confirming replies. I may stop by the dealer this next week and see if there is a delay that they can set so that it does not respond so quickly.

When I start my Veracruz in the garage, it normally takes about 30 - 45 seconds before the headlights go off on a sunny day, so I do not believe they are as sensitive.

Regards,

There is another thread on this somewhere.... I run into this problem all the time... and I mean all the time. If there is a shadow from the pillar directly on the sensor it will turn the lights on... it sucks wicked bad because I swear the people in front of me think I'm flashing them or something.

I went on a 50mi trip heading north. The sun was on the east side and I am not kidding you, my lights flashed on and off at least 25 times. My only gripe with the car so far.

If the lights switch on and off more than a time or two in a short time, I flip a piece of paper or other object on the dash to shade the sensor. Then, the lights stay on solid.

I noticed the same thing too.
It was later in the afternoon after taking off from work.
Not a big issue at all, but annoying.
Only if they could turn down the sensitivity of the sensor...

Just stick a few layers of Scotch 3M tape on it or a thin piece of printer paper cut in a circle to fit. This will reduce the light hitting the sensor and make lights come on sooner.

If you want it to be more sensitive to not bring on the lights till later, sand the top of the sensor cover to make it thinner and then a thin coat of clear nail polish to give it a finished look. You could also use the nail polish in a milky color on a non sanded thinner cover to reduce the light passing thru to get the lights on sooner.

To build in more hysteresis to the sensor and reduce flickering you will need to download the schematics and then locate the appropriate place to add a small capacitor across the light sensitive resistor, the value will best be determined my experimentation. This is a process bigger than I want to undertake.

I imagine that others will have many more suggestions as to how to change the sensors response.

This is also a way to get the day time running lights some people are asking for. Just block the sensor with black tape.

Or just have the lights to the "off" setting and turn them on when it's dark. Geez people. Do you still open the driver door for yourself??

This thread is nuts
