About part number A1189068500

A car headlight assembly is a vital safety component in the vehicle lighting system, fitted at the front to illuminate the road ahead and ensure the vehicle is visible to other road users in low light. It connects directly to the vehicle wiring harness and front body panels, delivering a clear beam pattern that the driver relies on for night driving and adverse weather.

To confirm this is the correct component, you must match part number A1189068500 directly against the number stamped on your original unit. This number is typically printed on a manufacturer label on the rear plastic housing or etched into the lens casing. Matching the part number is what decides if a part will fit, as vehicle specifications can vary.

Headlight units are commonly replaced due to collision damage, cracked lenses, or internal electrical failure. When replacing this component on the front right-hand side, a fitter usually needs the correct mounting screws alongside it to secure the unit firmly to the bodywork.

  • Part type: Headlight Assemblies.
  • Specification: mounting style Screws; country of origin United Kingdom.
  • Position on the vehicle: Right, Front.

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.
