Xenon and LED Headlight Adjustment in Dubai

Oncoming drivers are dazzled

A dipped beam set too high dazzles other road users and impairs their view of the road ahead. We lower a beam that sits too high to the height its headlamp is designed for.

The light ends short

A dipped beam set too low limits your own field of vision in the dark. We raise a low-set beam back to its designed height on both sides.

The beam rises with a load

Passengers, luggage and the pitch of the body alter how far the headlamps reach, which can dazzle oncoming drivers. A beam that still climbs with a full car signals a levelling fault. We fix the part that has stopped correcting it.

An automatic levelling warning in the cluster

A signal light or a text message in the cockpit alerts the driver to a levelling fault. Depending on the car, the headlamps then stay where they were or move to a home position and stay there.

We test the voltage supply to the actuator motors, the control unit and the axle sensor. The failed part is then replaced and the beam aimed again.

Glare from a xenon conversion kit

A xenon bulb fitted into a reflector headlamp built for halogen produced glare as high as 100 times the allowed limit in laboratory tests. We remove the kit and fit the bulb type the maker specifies, through our light bulb replacement service.

The full reach of the dipped beam

A headlamp mounted 60 cm high and set at a 1 per cent downward tilt lights the road for 60 m. We set the tilt so your dipped beam reaches that designed distance.

A steady beam under braking

Almost all cars with xenon headlights have dynamic levelling, which also reacts to acceleration and braking. Its actuator motors move within fractions of a second, so the beam holds its height as the car pitches.

No glare with a full car

A working levelling system lowers the cut-off line to suit the load. With every seat and the boot in use, the beam stays out of the eyes of oncoming drivers.

A corrected aim the car keeps

Once the cut-off line is set correctly, the levelling control unit stores that position as its new control value. The levelling then works from the corrected aim.

A longer, wider main beam

In a bi-xenon headlamp, one projection module gives both the dipped beam and the main beam. That main beam reaches further and lights the road edges better, and we centre it on the beamsetter marking.

A main beam that spares others

A non-dazzling main beam throws a square light pattern instead of the oval spot of a normal main beam. A pattern that is not set correctly can expose other drivers to extreme glare.

Test the lamps and read stored faults

We test every headlamp function and check the cover lenses for stone chips, scratches and dullness. Levelling and LED faults are stored in the control unit's error memory, and we document each entry before clearing it.

Prepare the car

We set the tyres to their prescribed pressure and place 75 kg on the driver's seat, with no other load. Cars with air or hydraulic suspension follow the maker's instructions.

Align the beamsetter

We centre the beamsetter box on the headlamp, within 3 cm vertically and horizontally. Its sight line is then squared to the car's long axis.

Set the forward inclination

The forward inclination is printed on the headlamp as a percentage. A value of 1 per cent means the dipped beam drops 10 cm over 10 m, and we set the beamsetter to that figure.

Adjust the cut-off line and main beam

We turn the adjusters until the dipped cut-off line touches the dividing line and its kink point sits on the central marking. The main beam centre goes on the same marking, and fog lamps are set level across the screen.

Measure the glare

A luxmeter reads the dipped beam glare, which stays at 1.0 lux or less for halogen and 1.3 lux or less for xenon. A headlamp that clearly exceeds its limit is replaced.

Call us to book a headlight aim check, and mention whether the glare or the short beam came first.

Headlight aim on a measured floor

Headlamp aim has its own floor standard, DIN ISO 10604. An error of 5 mm on the beamsetter screen equals 10 cm at 10 m, so we aim on a floor within its tolerances.

A beamsetter, not a wall

The lens in a beamsetter shortens the 10 m test distance to 50 cm. We read each beam on the aiming screen instead of a marked wall.

Xenon handled cold and switched off

The starting pulse from a xenon ballast reaches as much as 30 kV, and xenon lamp units operate at a high temperature. We turn off the ignition and let the lamps cool before we touch them.

Aim within the UN ranges

The UN lighting regulation sets an initial dipped-beam aim of minus 1 to minus 1.5 per cent below 0.8 m mounting height. Above 1 m, it sets minus 1.5 to minus 2 per cent, and we check each printed value against these ranges.

Headlamp washers tested

A working headlamp washer pump is clearly audible. When it stays silent, we check its voltage supply and fuse, then mend the wiring or renew the pump.

All makes, one test floor

We carry out xenon headlight adjustment, LED aim and halogen aim on all the makes we take in. The work happens at our single workshop in Dubai Investment Park 2.
