    Finished installing my headlights and noticed that the drivers side low & high beams don’t work properly like the passenger side. I’m using daveasa’s harness and made sure I connected everything correctly. Any idea what could be going on?

    I am not sure if I am only one but my 23 SR5 has same thing when it has hand/parking break engaged. When in park both lights come on but while engaged in hand/parking break, its like that too.


    Try disengaging parking break, but keep it in park obviously, and see if both lights set on.

    Assuming that was you, I also replied to the email. Post or send a photo of your high beam connector on the driver side. Positive is solid white and negative is white with a black stripe. It is easy to mix them up because they look so similar. The curve of the female h9 connector matches the tabs of the male h9 connector as well, offering some visual feedback if you see the tab on the shallow side.

    Mods, if you see this, perhaps it makes sense to move the thread over to my vendor forum?
