JAC S4 Headlight
About this part: Headlight
A headlight assembly comprises the housing, lens, reflector or projector optics, the light source (halogen bulb, HID burner or LED array), and increasingly a levelling motor, a daytime-running-light strip and a driver module. Sealed LED units are replaced as a complete assembly because the emitters are not serviceable.
Symptoms that usually point to it on a vehicle like the JAC S4:
- Standing water or persistent misting inside the lens.
- A dull, yellowed or crazed lens surface that no longer projects a sharp cut-off.
- Flicker, or one DRL segment out while the rest of the strip works.
Ordering this part
Specify the side, the light-source technology, the connector pin count, whether a levelling motor is fitted, and — critically for road legality — whether the vehicle is left- or right-hand drive. Beam patterns are asymmetric and a left-hand-drive unit fitted to a right-hand-drive car will dazzle oncoming traffic. Some assemblies also need coding to the body module after fitting.
Fitment is confirmed from the VIN and from the number on the part being replaced, not from the model name alone: engine variant, trim, market specification and mid-life revisions all change part numbers within the same model year. Send the VIN, the model year, the transmission type, whether the vehicle is left- or right-hand drive, and a photograph of the old part showing any number printed on it.
