How to Adjust Roadster Headlights

1. Park your Roadster 30 feet away from your closed garage door.
2. Turn on the headlights and shine them onto the door.
3. Open the hood and locate the adjustment screws. Depending on the make and model of your vehicle, there will be one or two adjustment screws. If there is just one, it will be a vertical adjustment screw and is normally located on the top of the headlight housing towards the back of the housing where the housing is bolted to the chassis. If there are two adjustment screws, the vertical screw will be located on the top of the housing towards the back of the housing and the horizontal adjustment screw will usually be located on the backside of the headlight housing assembly. Occasionally, depending on the design of the front bumper and fender, the horizontal adjustment screw will be located between the fender and the housing. If the screw is located on the backside of the housing, you will need a long screwdriver or socket extension to reach it. Roadsters also tend to have a high quality fit and finish, unlike most vehicles with a cheaper finish, and will likely have a rubber cap covering the adjustment screw, which you will need to pry off with your fingers.
4. Turn the adjustment screws to align the headlights. To do this, you'll need one of three tools commonly used on roadsters. Some roadsters, like the Honda S2000 can be adjusted using a simple Phillips head screwdriver. Other roadsters will require the use of a 10 to 12mm socket and socket wrench or a Torx bit screwdriver (a screwdriver with a star-shaped head. These screwdrivers are available at most auto parts stores). Turn the vertical adjustment screw clockwise to raise the headlight housing (and headlight beam) and counter-clockwise to lower the headlight housing (and beam). Turn the horizontal adjustment screw clockwise to turn the headlight housing (and beam) left and counter-clockwise to turn the headlight housing (and beam) to the right.
5. Adjust the headlights so that the center of the headlight beams sit at the bottom of the door where the door meets the ground and until both headlights overlap each other by 50 percent. From 30 feet away, you will have the proper headlight adjustment for your roadster.
