Default Headlight low-beam aim low. But high-beam okay. What to do?

My car is fully stock, with all options available to me (cold weather package not available here). The low-beam triple-LED headlights are aimed way too low compared to all my previous cars, and where they should be. BUT high-beam is aimed properly. So if I adjust the low-beams up, my high-beams might end up lighting up the trees, not the road.

Has anybody adjusted the headlights up on a fully stock car (not lowered at the front)? If so, are the high beams still lighting up the road fine? And if you can be specific as the number of turns on the screwdriver, it'd be good too to have an initial adjustment reference. Thx.

Had mine adjusted last week (raised). There are two adjustments above the headlights for raising/lowering and to sum left or right. The adjustment wheels are kinda far down to adjust so my dealer took all if 5 minutes. They have a measurement line painted on the wall and they back car up so many feet until the light dues t dip below the line.

Thanks man. I always adjust my cars and bikes (when needed) at a street near my house with walls on both sides and in front, so I can adjust them perfectly without bothering oncoming traffic, with an ever so slightly downward slope (visible on the side walls). But wanted to have an idea how much initial adjustment so I don't have to get out of the car that much; it's been cold and I'm quite vulnerable of getting sick right now. But glad somebody else had them adjusted, meaning they're indeed low from the factory. I bet Lexus didn't plan to produce the stupid car raised like a 4x4 at the front. Ha ha. The stance on the rear is perfect. In front, not so much. Anyway, will probably wait until it warms up a little, but will get it done. I know where the adjustments are, but thanks for the explanation anyway. I'm probably only mess with vertical aim, but will see how they're aimed on that long street. Thanks again.

Anyone have a spec on height of beam at a set distance? Mine seem low. Can you adjust height without it affecting the side to side?

  • Inflate the tires to the appropriate pressure.
  • Unload the trunk and vehicle, ensuring that the spare tire, tools and jack are in their original positions.
  • Sit a person of average weight (68 kg, 150 lb) in the driver's seat.
