Use a level to determine the proper horizontal aim and adjust the aim until its level.

The aim can be moved left or right by turning the adjustment screw with a screwdriver. The aim will shift to the left when rotated clockwise and to the right when rotated anticlockwise. Don't forget to use masking tape to indicate the adjustment screw's location so you can quickly locate it again if additional adjustments are required. Do the same procedure as the other headlight.

Important Precautions to take while adjusting the Headlight on Jeep Wrangler JL!

Here are some precautions while you are wondering “How to adjust the headlights on Jeep Wrangler JL”:

  • Always wear protective gear such as gloves and eye protection while adjusting the headlights to keep you safe from danger.
  • Do not touch the headlights as it may be possible that any oil or moisture on your fingers might damage the bulb and result in reducing the lifespan of the bulb.
  • Never start working on a hot headlight instead turn off the engine and let the headlight cool down. This will help avoid any burn injury on your fingers. Also, a heated headlight expands a little and it proves to be difficult to remove it.
  • Use suitable tools for the right task to make things easier. Trying to use the wrong tools can damage the headlight or the adjustment (threads) of the screws.
  • Never over-tighten a screw to try to secure it. You need to exert the right amount of pressure and leave a little room for the screw to unwind 1-2 treads. This way you will never damage the headlight or the top of the screw.
  • While adjusting the headlight, make sure that the vehicle is facing toward a wall or a garage door. Facing your Jeep towards the road can unexpectedly blind any drivers passing by and result in an accident.

By taking the necessary steps and following the above-mentioned safety rules. You can work in a safe and secure environment while successfully adjusting the headlights.
