How adjust headlights.

I got a 14 Tacoma. I need to know witch way to have the lens go down. I got leds in it. Plus is it the top or the bottom thing. Please need help.

 

You shouldn’t need to aim your lights down after a proper bulb change. Your lights with LEDs likely have significantly increased glare, making it unsafe for oncoming traffic. However aiming them down doesn’t really solve the issue and reduces your headlight distance projection leading to unsafe performance for you. Presumably you bought LEDs to increase performance. I’d highly recommend a halogen upgrade instead:

But to answer your question, the adjuster is here on the back of the light:

 

What’s the top one for?

 

Horizontal adjustment

 

Yep, highly advised not to play with that one as it is a royal PITA to return to center.
