    Adding auto headlamp feature to 2020 4Runner non limited or Pro

    All my other vehicles have auto headlights. This is the only grip my wife has with my 20 Venture.

    Has anyone added dded the feature

    Could it be this simple or is there more parts involved

    I know its Honda but
    I had auto headlights on my 08 Acura TL Type S and my buddy's TL did not. He added the switch and gained the feature

    Yes I know how easy it is to just use the switch


    Quick research
    TRD PRO and Limited use

    Headlamp Switch - Toyota (84140-35171)
    Multi-Function Switch, Switch Assembly Headlamps
    Limited package. 4Runner. Trd-pro. With auto headlamps.
    Notes: Includes Headlamp, Fog Lamp And Turn Signal Switch.

    Venture and below use
    Headlamp Switch - Toyota (84140-35181)
    Multi-Function Switch, Switch Assembly Headlamp
    4Runner. Sr5, trail package. Without auto headlamps.
    Notes: Includes Headlamp, Fog Lamp And Turn Signal Switch.

    I would figure that you’d also need something that senses when it’s light or dark enough for the lights to on or off.

    sounds simple to build. perhaps trigger off the ambient sensor to a 12v relay to the light switch. but the switch would have to be on the on position all the time and the sensor and relay will handle the rest :)

    I'd like to do the same. It's ridiculous when you look through the owners manual and see all of the different headlight configurations. You'd think Toyota would save a few bucks just making everyone have the same setup with Auto headlights.

    Please! If someone figures this out it would be awesome... so disappointing that my base base model ‘05 corolla has auto headlights and my $40,000 SUV doesn’t!!

    Why not just leave the headlights on all the time? They turn off automatically.

    I felt the same when I bought my 2019 TRD OF but now I just deal with it. From what I saw in previous posts even changing the switch on the column doesn't fix the issue and it could be in the software of the truck. I have just gotten used to leaving the lights on and not worrying about it. The latest issue I have is the sun reflecting off the hood scoop when driving lol

    Yeah I’m not willing to pay that much for my 2020. I’ll wait cause $5-$10 seems worth it.
