    Months ago I installed a Big Ass (brand) LED in my Summer home.

    Began to notice that when dark out, and taking my car out, the screens would not dim. Unless I switched them to manual.
    Waited half an hour of driving to no avail.

    Finally determined that the super bright LED was making it think it was daylight.

    Asked service; they were oblivious.

    Then drove to Winter home and charged on way at dark at Cincinnati (Blue Ash) ... it is lit with very bright LED's. But probably 16 feet up. not 7' like my garage.

    As I left there, same thing happened.

    Spent weeks at Winter home where there's no LED and the problem didn't manifest itself.

    Anyone else see this?

    Is it a design flaw or do I need a new sensor in the rear view mirror?

    Funny you should bring this up.... I noticed just the other day (about a week after installing LEDs in the garage) that when I left for work in the morning the screen was stubbornly on Day mode. Even after I backed out and into the street, when I toggled it to Auto it wouldn't flip to Night mode (at least not fast enough for a man of my patience). So I just locked it in Night and started my drive. About 5 minutes later I toggled it into Auto and it dutifully remained there and has been fine since.

    So I just made note of it in case it repeated. I realized-- after reading your post-- that I think that particular morning I switched on the LED lights but other mornings I just let the regular bulbs (on the openers themselves) do the work.

    Thanks for posting-- no, you're not insane (or ludicrous).

    Early versions of the firmware had the screens constantly flipping from Day to Night mode. Driving through relatively short underpasses for instance. I think they've added some hysteresis in the software to prevent this, so "fooling" it with bright lights at night is probably causing it to start up in Day mode, then you have to wait for it to flip modes.

    It's funny, I always have the opposite problem. My screens are almost always in night mode when I start the car in my garage, even in the middle of the day. Then I back out of the garage and can barely see anything (like the backup camera!) until it switches. Fortunately it almost always switches within a few seconds of being outside so it's a minor problem.

    Yeah, I've found the transition from Night to Day is relatively quick. Probably to address those coming out of garages and underground parking lots during the day. The flip from Day to Night seems to take a bit longer. The software engineers probably didn't anticipate the OP's Big Ass LED garage lights! My car is already in Night Mode in the garage, even with my "normal" overhead lights on.

    I have 80,000 lumens of Led lights in my home garage and my car does the same thing. It takes the car about ten minutes to compensate.

    BTW $400 for those Big Ass LED's is a big ass rip off for 13,000 lumens @ 122 watts = 106 lumens per watt. The Tek PRO's are actually a little more efficient 20,000 lumens @ 216 watts = 92.6 lumens per watt.

    Financially the Big Ass LED's cost only yield 32 lumens per dollar while the Tek Pro yields 134 lumens per dollar.

    I bought these instead: Tek Pro Black Ultimate Shop Light

    The Tek PRO delivers more lumens per watt than regular fluorescent lamps or incandescent bulbs! High output, energy efficiency and quality of light make this the ultimate garage, shop, workbench or craft area light fixture. T5 HO fixture with 4 lamps produces an amazing 20,000 lumens, while a standard 4 lamp T12 fluorescent fixture produces 11,800 lumens and a 200 watt incandescent standard household bulb only 3,900 lumens (varies by lamp type). “Daylight” 6500˚ K lamp color makes them very pleasing to the eye. They also feature a high color rendering index (CRI) of 84. Tek PRO fixtures are made from rugged diamond plate aluminum and have a durable powder coated finish. State-of-the-art reflectors are made from 95% reflective German aluminum. This unique high-end embossed material offers unparalleled output, reflectivity and diffusion. “Daisy chain” feature allows multiple fixtures to be plugged in together (not to exceed 12 amps). 120 volt/216 Watts/1.8 amps per fixture. 1 year warranty on ballast components. Made in the USA.

    Features:


    • 4- 54 watt 4’ T5 daylight lamps (6500˚K)
    • On/Off switch
    • 95% Reflective German aluminum reflectors
    • Durable powder coated aluminum diamond plated housing
    • 10ft grounded 120 volt power cord
    • Daisy chain feature allows multiple fixtures to be plugged in together
    • 1 year warranty on ballast components.
    • Dimensions: 48"L x 12.75"W x 3"H
    • Made in the USA
    • $149.00

    I posted on the main Tesla Forums.

    I have the same but opposite issue. My garage is dark, so when I leave in the morning and pull out in bright daylight, the lights on my car do not shut off for 30 min or so.... It seems the latest firmware changes the hysteria on the light sensor.. maybe people were having issues with lights turning off and on in storms, I dont know but its annoying.

    I've always had problems like this with the headlights. I believe it has to do with the fact that the sensor is in the windshield. Most, if not all of my past cars have had the ambient light sensor on top of the dash so that it receives light from more directions. I find that as fall/winter approaches and the sun is getting lower on the horizon, if I'm driving in any direction other than directly in to the sun, the sensor cannot "see" the sunlight and my headlights stay on. It can be broad daylight and everyone else's lights are off, but because my windshield sensor is in the shadow of the sun, it leaves the lights on.
