Headlight System - Except Lancer Evolution — Mitsubishi Lancer Evolution X (2007-2016)

Scheme 1

Scheme 1: GENERAL INFORMATION

As for headlight assembly, a type with halogen bulbs for the high-beam and low-beam and a type with a discharge bulb for both high-beam and low-beam are established.
The halogen bulb type headlight assembly employs the four-light type integrated with the headlight (low-beam), headlight (high-beam), front turn-signal light, and position light. The dimmed headlight (low-beam) is also used as a daytime running light.
For the discharge bulb type headlight assembly, the headlight assembly with two headlights has been adopted which incorporates the projector type headlight (low-beam/high-beam), daytime running light, front turn-signal light, and position light. Also, the headlight manual leveling system has been adopted. The switching of headlight (low-beam/high-beam) is performed by the driving of light-shield in the projector unit using the signal from lighting switch.

SERVICE PRECAUTIONS < DISCHARGE HEADLIGHT >

Before checking the discharge headlight related parts, be sure to read the following warnings and precautions carefully, and then perform necessary operations.

WARNING

Do not touch the socket and the connector while the headlights are on. High voltage is applied to the bulb socket and connector during headlight operation. The operator may be burnt or dead due to an electric shock by high voltage. Do not attempt to use a tester to check them. If the bulb socket and connectors should be inspected using a tester, the operator may be burnt or dead due to an electric shock by high voltage. Do not turn ON the headlights while the controller or the bulb is removed. If the headlights are turned ON with the controller or bulb removed, the operator may get burned by the high temperature of the bulb. The operator may be burnt or dead due to an electric shock by high voltage. Before service work, turn the lighting switch OFF and disconnect the battery terminal and the controller connector in a dry place. Do not touch the components with wet hands. If you work on the components with wet hands or in wet conditions, the operator may be burnt or dead due to an electric shock by high voltage.

WARNING

Do not illuminate the bare headlight bulb. (Do not illuminate the headlight using other than the vehicle power supply.) If the headlight bulb illuminates without fitting it in the headlight unit, it may burst due to rise in its internal pressure.

CAUTION

When reusing the controller with the discharge headlight damaged, observe the inspection procedures for the related parts of the discharge headlight before determining the reusability of the controller. If you fail to observe "How to check discharge headlight components," the vehicle may be damaged.

Inspect for rusted or faulty headlight assemblies.
These conditions must be corrected before a satisfactory adjustment can be made.
Inspect tire inflation, and adjust if necessary.
If the fuel tank is not full, place a weight in the trunk of the vehicle to simulate weight of a full tank [3 kg (6.6 pounds) per gallon].
There should be no other load in the vehicle other than driver or substituted weight of approximately 68 kg (150 pounds) placed in driver's position.
Turn the headlight leveling switch to the switch position "0." < Vehicles with headlight manual leveling system >
Thoroughly clean headlight lenses.
Place the vehicle on a level floor, perpendicular to a flat screen 7.62 m (25.0 ft) away from the bulb center-marks on the headlight lens.
Rock vehicle sideways to allow vehicle to assume its normal position.
Bounce the front suspension through three (3) oscillations by applying the body weight to hood or bumper.
Set the distance between the screen and the bulb center marks of the headlight as shown in the illustration.
Four lines of adhesive tape (or equivalent markings) are required on screen or wall: Position a vertical tape or mark so that it is aligned with the vehicle center line. Measure the distance from the center-marks on the headlight lens to the floor [reference value: 679.5 mm (26.75 inches)]. Transfer the measurement to the screen. Horizontal tape or mark on the screen is for reference of vertical adjustment. Measure the distance from the center line of the vehicle to the center of each headlight. Transfer the measurement to the screen. Vertical tape or mark on the screen with reference to the center line of each headlight bulb.

Standard value < Vehicles without discharge headlight >: (Vertical direction) Horizontal line (H) ± 50.5 mm (± 2.0 inches) (± 0.38 degrees angle) (Horizontal direction): ± 126.4 mm (± 5.0 inches) (± 0.95 degrees angle) from the axis, which is 266.1 mm (10.5 inches) (2 degrees angle) rightward from the vertical line (V) Standard value < Vehicles with discharge headlight >: (Vertical direction) 53.2 mm (2.1 inches) (0.4 degrees) below horizontal line (H). ± 50.5 mm (± 2.0 inches) (± 0.38 degrees angle) (Horizontal direction): Elbow point intersects the vertical line (V). ± 126.4 mm (± 5.0 inches) (± 0.95 degrees angle) CAUTION: Do not cover a headlight for more than three minutes to prevent the plastic headlight lens deformation. NOTE: High-beam pattern should be correct when the low-beams are adjusted properly.

LUMINOUS INTENSITY MEASUREMENT

Set the headlights to high-beam.
Using a photometer, and following its manufacturer's instruction manual, measure the headlight center intensity and check to be sure that the limit value is satisfied. Limit: 40,000 cd or more {When a screen is set 18.3m (60 feet) ahead of the vehicle} NOTE: When measuring the intensity, maintain an engine speed of 2,000 r/min, with the battery fully charged. There may be special local regulations pertaining to headlight intensity. Be sure to make any adjustments necessary to satisfy such regulations. If an illuminometer is used to make the measurements, convert its values to photometer values by using the following formula. I =E x r 2 I = intensity (cd) E = illumination (lux) r = distance (m) from headlights to illuminometer
