Manual level control head lights

What setting do TRD owners keep their headlight level during normal driving conditions; no load with stock wheels? Mine was at 3 when I bought it and that's where I've left it. I'm hoping that's factory default. I would hate to be off and thus blinding on coming vehicles. Sorry haven't looked at manual.

 

Not TRD but regular 4wd with 2.5” level. The happy medium seems to be 1.5 on mine. When I had my stock 2wd 0 was the sweet spot. This is on 285/55/20 tires. At 3 you probably can’t see anything. The best way to find out on your particular truck is to play with it.

 

If the truck is completely stock 0 is the correct “factory” setting.

 

Measure the height of the center of the headlamp, and adjust the top of the beam against a wall so that they're about the same or just below that on a flat/level surface at a distance of 25ft.
