    Has anyone thought about (or actually done it) installing some sort of light sensor that would automatically turn your headlights on and off based on amount of light outside? I had this on my Yukon and loved it - to the point where I would forget to turn on my lights when I got my Tacoma. So, now I just leave them on all the time...

    same here I just leave the headlights and foglights on all the time, do wish there was some sort of sensor the only activate during low light situations.

    There has to be someone in this community that is good enough with electronics to figure this one out... :)

    The light sensor part would be pretty easy to accomplish... it's a simple circuit. The tricky part is the logic that avoids all of the gotchas. For example:

    If you drive under a bridge for a few sec, you don't want them to turn on.
    If you start the truck in the dark they should come on immediately.
    If you drive through a construction zone with really bright lights you don't want them to turn off.
    If it's dusk you want them to come on at some point and stay on, not flicker as you drive through shadows.

    These are all solvable situations, but requires more than a light sensor to accomplish. It could be done with a simple $10 microprocessor if someone had the time to write and test the code.

    However... I found this on a Lexus forum... it might work... and under $40 too!

    I used to leave mine on too, but it hurts your gas mileage. I save at least 1 MPG by keeping them off.

    How does it hurt your gas mileage?


    Maybe you could take one off a newer Camry... perhaps one that was wrecked... then just install it on the Tacoma. Or maybe even just buy one from a dealer. Not sure how much that would cost - but worth a shot.

    Everyone here already knows that the AC will hurt it, but all the major electrical loads also hurt the mileage.

    Yea - but why? Because of the electrical draw on the Alternator that causes the engine to work harder to replace the energy? Maybe I just answered my own question.... Hey, I'm sick at the moment - so my head isn't all that clear.

    Cool - thanks... so back on topic... Anyone out there try to take an autolight function from a newer Camry and put it in a Taco... They are pretty close with regard to interior...
