  • Aiming Headlights for a truck

    Currently my truck has 1.5in level kit making the front ride height half inch higher than the rear. Currently my headlights are aimed down 5 inches lower than the height of the center of my projector which is 40inches at 25 feet. Reasoning is to minimize the blinding of drivers side and rear view mirrors that drive in front of me which in turn decreases the distance of my lights. I have had zero issues with oncoming traffic. I am contemplating on taking out the level kit causing my truck to have just over an inch of rake or putting in a 1in level kit to make it perfectly leveled. My thoughts are that if i have rake i would have to compensate my lights facing down which would also hinder my distance because i dont want them be aiming upward? But if i make the truck leveled out so the ride height is the same front and rear i would be able to get maximum distance without blinding side mirrors and rear view mirrors least amount as possible.

    ​​​​

    Any thoughts ideas or opinions on this would be greatly appreciated!!

    Setup is 08 GMC sierra with TRS tuned sti-r clear lens rx350 projectors with Osram Nightbreakers stock size tires and stock suspension currently with 1.5in level kit spacer in the front

    The adjusting of the headlights should have nothing to to with the suspension setup or level kit. It should be a completely different process everytime you change the ride hight. If you set up the headlights to a 1.2 to 1.5% drop it should be fine.

      It does because it affects how high the center of my light is. If I did a 2 in drop my lights would blast the roofs of cars I drive behind causing me to have to do a 5in drop which drastically reduces my range. I have gone back to stock height and now I'm doing a 3in drop and have increased my range while still staying just barely below side mirrors of cars that I drive behind. I do care about not making people's mirrors light up like the 4th of July. Anyways thanks for the input but to conclude what I found putting it back to stock height I have been able to increase my range without blasting rear view mirrors of the cars I drive behind.

          It was at 40 inches now it sits 37 inches. Those few inches made a world of a difference
