About part number MY42-13W029-GB

This part is a front right-hand side headlight assembly, which forms a vital part of the vehicle lighting system. It mounts to the front bodywork and connects directly to the main wiring loom to provide forward illumination and front indicator functions. When working correctly, it projects a clean light pattern for night driving and keeps the vehicle clearly visible and legal on the road.

To confirm this is the correct item for your vehicle, you must match the engineering part number MY42-13W029-GB or one of the cross-reference numbers LR144118, 89916102, or MY4213W029GB directly with the code stamped on your existing unit. Manufacturer numbers are usually printed on a sticker or moulded into the plastic housing on the rear or underside of the lamp casing. Matching these exact numbers is the only way to guarantee correct fitment.

Headlights are typically replaced after front-end impact damage, when the plastic lens becomes severely faded, or if internal electronic components fail. When fitting a replacement headlamp, mechanics often install fresh fixing clips or replace damaged mounting brackets to ensure the unit aligns correctly with the surrounding body panels.

About this kind of part: headlamps

A headlamp is a sealed unit holding the main beam, the dipped beam, the daytime running light and usually the indicator. The light source is either a bulb, a gas discharge capsule or an array of light-emitting diodes, and the three are not interchangeable within one lamp housing. The lens is polycarbonate with a hard coat on the outside, the housing is plastic, and the whole unit hangs on moulded lugs that bolt to the slam panel and the inner wing.

Why people replace one

  • An impact has broken the lens or cracked the housing, so water gets in and the unit mists up.
  • The hard coat on the lens has broken down and the surface has gone yellow and cloudy, which cuts the light output and fails an inspection.
  • A mounting lug has snapped, which is common because the lugs are the first thing to give in a light front-end knock. The lamp then sits low or loose.
  • Condensation sits inside the lens after rain, because a seal or a breather has failed.
  • The adjusting mechanism behind the lamp has stripped, so the beam cannot be set.

Fitting it

  • A headlamp is reached with the front bumper cover off on most cars, and is held by three or four bolts.
  • The beam must be aimed on a proper beam setter after fitting. A lamp that has been swapped and not aimed will dazzle oncoming traffic and will fail an inspection.
  • The adjusters are plastic and are easier to set with the lamp loosely held before the bolts are tightened.
  • If a mounting lug on your own lamp has broken, the repair brackets sold for the job are a temporary measure rather than a fix.

Making sure it is the right one

  • Match the part number on the lamp. Within one model the bulb, discharge and diode versions all share the same body shape and will plug in, but the car will not light them correctly.
  • A lamp built for a market that drives on the left and a lamp built for a market that drives on the right have different beam patterns, even where the part looks identical. The pattern is marked on the lens.
  • The lens marking also records the approval, and comparing that marking with your own lamp is a quick way to confirm the two are the same specification.
  • Count the connector pins and compare the block shape with your own lamp before buying.

What to look for in the photographs

A Part number — On a printed label on the back of the housing, or moulded into the plastic. This is the number to match.
B Lens marking — Etched into the lens itself: the approval marks and the beam pattern. Compare it with the marking on your own lamp.
C Mounting lugs — The moulded arms that bolt the lamp to the car. Check each one is whole, because a snapped lug is the most common fault and the hardest to see.
D Connector block — The plug on the back. Count the pins and compare the shape, as a different light source means a different block.
E Lens surface — Look across the lens at an angle rather than straight on. Fine crazing and a breakdown of the hard coat show up in a raking light and vanish in a flat one.
F Housing and seal — The joint where the lens meets the housing, and the rubber covers on the back. Water gets in where these have been disturbed.
