A LITTLE HISTORY:
Sealed beam headlamps were introduced in the 1930s to provide a consistant quality of headlamps. Prior to that, headlamp design was left up to the vehicle manufacturer and lighting ability varried greatly.
The problem with sealed beams is that the lens, reflector and fillaments are all part of a bonded assembly. When the filament burns out, the entire lamp is discarded. Consequently, the sealed beam has become a commodity. Our high quality Quartz Lens and silverized and polished alumonum reflector will probably out live the vehicle.. We say that our lamps are twice as bright on high beam. Refer to the Isolux drawings.

OPTICALLY AIMING ECE HEADLAMPS
ECE headlamps are intended to be aimed optically. This is a superior method to aim headlamps because it eliminates the effects of manufacturing tolerances and variations in filament placement in respect to the aiming lugs. Consequently, ECE headlamps do not have any aiming lugs.
Many auto repair businesses have equipment to aim headlamps optically, but not all. The advantage of this equipment is that aiming can be done indoors with the lights on and uses considerably less floor space.
To aim these headlamps yourself is relatively simple. Here are the steps.
· Adjustment of these headlamps is achieved by turning the two screws on the headlamp frame. The screw at the top or bottom will adjust the up-down aim, and the screw at the side of the lamp will adjust the left-right aim.
· This is best done at night.
· Position your car on a level surface. Pointing at a garage door or a wall, place the vehicle about 25 feet from the wall.
· Turn the headlights on high beam.
· Using a yard stick or a tape measure, as close as possible to the left side head lamp, measure the distance from the floor to the cutoff line of the lamp beam. Note this distance.
· Looking at the light pattern on the wall, adjust the left-side headlamp left or right so that the “Hot Spot: is in line with the headlamp. Try to get it correct within a couple of inches.
· Go to the wall and mark the height of the headlamp and mark it with tape, or if you own the wall, a marker.
· Adjust the headlamp so that the hot spot is centered on the mark.
· Measure the distance between the headlamps. Note this number.
· On the wall, measure to the right the distance between the headlamps and mark the wall.
· Looking at the light pattern on the wall, adjust the right-side headlamp left or right so that the center of the “Hot Spot: is at the mark. Try to get it correct within a couple of inches. This should result in the beams of both headlamps being parallel to the longitudinal axis of the vehicle and to each other.
· Using the same height measurement you used for the left-side headlamp, adjust the right-side headlamp up or down so that it is the same height as the left-side headlamp.
