SEETECH´s DRAGON® is a case‐free headlamp aiming system. Dragon is composed of a state‐of‐the‐art machine vision system, it´s very own electronics, IT equipment and regulation software.
Dragon‐FT: equipment for carrying forward photometric tests by means of machine vision;
Dragon‐TS: equipment designed for quality control areas;
Dragon‐PR: equipment designed for assembly plants, where time is of the essence;
Dragon‐TSPR: combination of TS and PR equipment;
Dragon‐ITV: designed for vehicle inspection authorities.
For the first time in headlamp aiming history, it is no longer necessary to place the equipment in front of the headlamp in question. The system will remain motionless, avoiding damages and wearing of materials.
Through acquisition of a real‐time image, the software calculates the exact position of projection for the headlamp, whilst the power tools adjust the elevation of the headlamp.

The Dragon equipment is able to regulate passing and driving beams, as well as fog lamps, regardless of whether these are xenon, halogen, AFS, LEDs, etc.
The system, which will never become obsolete, (through personalization) is capable of adjusting any kind of headlamps. The criteria that the equipment follows in order to determine the correct adjustment are the headlamp standards. These standards can be later adjusted to suit design specifications, at our client´s request.
Adjustment speed per headlamp is between 2 – 8 seconds (speed average based on 9 different models from various manufacturers). Several communication options: serial, parallel, RS 232, RS422, RS485, wireless, Ethernet.
The criteria that the equipment follows in order to determine the correct adjustment are the headlamp standards.
These standards can be later adjusted to suit design specifications, at our client´s request.
Our equipment meets a wide range of standards from all of ECE (European) standards to SAE (USA, JAPAN).
A tridimensional machine vision system automatically calculates headlamp positions and adjusts internal values for perfect regulation, with an adjustment precision of +/‐ 0.5 cm at 25 meters.
In view of our clients´ necessity to be able to integrate a headlamp aiming system in areas where the available space makes it impossible to install a conventional system, SEETECH has designed and created the DRAGON.
DRAGON can be installed, for example, in between alignment stands and dynamometer systems, as in Ford Valencia´s case.
DRAGON´s additional values:
‐ Time taken to find headlamp = 0
‐ Time taken to position equipment in front of headlamp = 0
‐ Time taken to switch between headlamp 1 and 2 = 0
‐ Time taken to return to parking = 0
All of DRAGON´s time courses in the headlamp aiming process integrate or overlap with other processes that require much more time.
Using Ford Valencia as an example, the equipment is ready to begin aiming before the wheel alignment process has finished centering the vehicle and the headlamp aiming process is over before the vehicle´s convergences are complete.
From the moment the vehicle is centered, the equipment is ready to aim and takes the same amount of time as an operator would to utilize the power tools, aim the first headlamp, move to the second, aim the second headlamp and hang the tools back in position.
Preventative maintenance is not required, as the equipment disposes of an auto‐calibrating system, so maintenance personnel will not have to calibrate the camera.
Any equipment breakdowns can be repaired in just 5 minutes maximum.
The event of a serious system breakdown will not, under any circumstances, prevent the vehicle from continuing forward.
