CURRENT BAY - The aiming bay number that is displayed at the bottom of the monitor screen that has had the floor slope entered.
DRIVER SIDE - The left side of the vehicle, or the side the driver normally is seated in a vehicle built for the United States.
EUROPEAN BEAM PATTERN HEADLAMPS - The pattern is most identifiable by the flat upper cut-off of the light beam.
EXPERT MODE - The operation mode that bypasses explanatory screens in the aiming process.
FACE OF THE HEADLAMP - The outer lens of the lamp.
FACTORY CALIBRATION - The tuning adjustment of the aiming unit at the manufacturing facility.
FBA METHOD - The S.A.E. recommended method of aiming headlamps by measuring percentages of light at particular test points on an aiming
screen at the prescribed distance of 25' from the producing light source.
FIDUCIARY MARK - A manufacturer mark designating the optical center of a lamp.
FLOATING AXLE - The pivoting axle in the base of the aiming unit.
FLOOR SLOPE - The deviation from "true level" of the floor of the aiming bay. This value is measured in degrees.
FOG LAMPS - Lamps specifically designed for use in foggy weather.
FRACTIONAL GRADIENTS - The bands of light around the most intense area in the beam pattern. These are usually defined in percentages of
the lamp maximum intensity.
G2 SPLIT IMAGE TRANSIT AND TARGET - A HOPPY® product used to measure grades and slopes.
GRID LINES - The lines used in a lamp to refract or reflect light into a specific area of the beam pattern.
HEADLAMP ADJUSTMENT SCREWS - The screws used to adjust the position of the headlamp. There is usually one horizontal adjustment
screw and one vertical adjustment screw.
HELP SCREENS - The explanatory screens that are made available to describe each step of the setup or aiming procedures.

LASER ALIGNMENT - The method of using the laser to align the aiming unit to the vehicle, by placing the laser on a point representative of the
centerline of the vehicle. Moving the laser up and down that centerline, while adjusting the aimer base. This is repeated until the laser accurately
follows the centerline of the vehicle.

MONITOR HOUSING - The case holding the monitor.
NOVICE MODE - A mode of operation in which the aiming process is explained, by text screen, step-by-step.
