Optical headlamp alignment is the measurement of the position of the lamp by means of an electronic or mechanical system. The Symtech systems are designed around and incorporate a precision lens, which has a prescribed focal length. Systems of this nature measure the light emitted from the lamp and assess the position of the light at 25 feet in front of the vehicle. Previous to 1990, all lamps were manufactured with aiming nibs, that is, the bumps on the outer lens of the lamp that destroyed your bug sponge when washing the vehicle. The nibs were for the distinct purpose of registering and positioning a mechanical alignment system to the lamp lens using suction cups. Aiming pads were on all US headlamps until 1991. The Grand Prix was the first onto the market without aiming pads and utilized level vials. This has rendered the mechanical alignment devices with the suction cups obsolete.
Today, most automobiles are manufactured with headlamps that do not have aiming nibs and the truck market is gradually moving in that direction. All Symtech systems can align lamps with or without aiming pads.
All Symtech systems are designed for modular component replacement, with repairs 98% of the time performed at your facility, by you. Should any component of the system malfunction or become damaged, a phone call to Symtech Technical Assistance can assess the problem, advise of replacement component and instruct you on the repair upon receipt of the component. Downtime is costly. The shipping of components instead of a complete unit, coupled with your ability to do repairs on site, allows for lower shipping costs and less time that your Symtech system is offline. Symtech’s 24-hour turn-around of replacement components not only saves you money but assures you of quality parts designed specifically for your equipment.
