Toyota Celica Left-Hand-Drive Headlight Spec is...
Driver's side should be facing directly forward - best for seeing the road and NOT blinding oncoming traffic so horribly.
Passenger Side will be the same height and facing very slightly to the right - best for viewing signs and notifying pedestrians that you are headed towards them.
From G.E., is the recommended way to check headlight aim...
1. Put your car on a 35-40 foot stretch of flat or evenly sloped pavement such as a driveway facing a wall or garage door.
2. Shine your low beams on the door from 2 to 3 feet away and outline the bright spots on the door with a pencil or tape.
3. Back the car to about 25 feet from the door. The top of the low beams should shine no higher than the top of the marks on the door or lower than the center of the marked circle. If you have only two headlights, the high beams are automatically aimed when you aim the low beams.
For most accurate aiming take your vehicle to a professional. If, on the other hand, you're a "do-it-yourselfer", follow these instructions from G.E.:
Remove the outer trim for access to the adjustment screws. To raise the beam turn the top adjustment screw clockwise; counter clockwise to lower the beam. Turn the side adjustment screw clockwise to move the beam to the right and counterclockwise to move it to the left .
Bring each beam into its final position by turning the adjusting screws clockwise so the headlamp will be held against its tension springs when the operation is completed.
If your lights continue to be out of adjustment, consult a service technician.
wait, so there is a horizontal adjustment?
or is that just a general rule?
