1998 Toyota Altezza Headlights — What They Do and How to Look After Them

Headlights are absolutely relevant and fitted to the 1998 Toyota Altezza (chassis SXE10/GXE10). This is supported by Toyota’s 1998 Altezza owner’s manual and Toyota Electronic Parts Catalogue listings for complete headlamp assemblies, bulbs, and levelling components, plus period Japanese-market brochures showing projector-style lamps. Roadworthiness rules like ADR 13/00 in Australia and Waka Kotahi/NZTA WoF requirements also mandate operational headlamps, so any roadgoing 1998 Altezza will have them.

On this model, the headlights provide low- and high-beam illumination for safe night driving and visibility in poor weather. Most cars were supplied with halogen projector low-beams and a separate high-beam reflector, with some trims offering factory HID low-beams. The assemblies are polycarbonate for impact resistance and usually include an electric or manual beam leveller so the driver can adjust aim when the car’s loaded up. Good headlights help the Altezza’s sharp steering and chassis feel translate into real-world confidence after dark.

As part of routine servicing, the headlights deserve a quick health check. Lenses can haze or yellow from UV, bulbs dim with age, and wiring or earths can corrode. For halogen globes, it’s smart to replace in pairs and avoid touching the glass with bare fingers. If the car has HID, expect the capsule, igniter, or ballast to age over time—dim, pinkish, or flickery low-beam is a giveaway. Always verify beam aim after any bulb or housing change, poor aim can fail a WoF or cause glare for oncoming traffic.

• Inspect lenses each service: if they’re cloudy, restore with a proper kit and finish with a UV sealant, or consider new housings if the coating is gone.
• Check for moisture inside the lamps, clean breather ports and replace rear caps or seals if there’s condensation.
• Verify all functions: low/high beam, park light, and levelling switch. Fix any flicker or dullness before night trips.
• Use quality, ADR/NZ-compliant bulbs matched to the car’s spec (halogen vs HID). Avoid over-wattage globes that can cook the wiring.
• Have beam aim set on a flat surface or by a workshop beam-setter to meet ADR/NZTA patterns.

If anything seems off or access is tight, an auto electrician or trusted mechanic can sort bulbs, aim, and wiring without drama.

What bulb type does a 1998 Toyota Altezza use?

It depends on trim and market. Many 1998 Altezza models use a projector low-beam (halogen) with a separate halogen high-beam, while some trims run factory HID low-beams. The sure way is to check the owner’s manual, the markings on the rear caps, or the Toyota parts catalogue using the VIN. Matching like-for-like (halogen vs HID) keeps the beam pattern legal and effective.

Why are my Altezza headlights cloudy or yellow?

The polycarbonate lenses can degrade from UV and road grime, which scatters light and weakens the beam. A proper restoration (sand, polish, and a UV hard coat) often brings them back. If the factory coating is too far gone or the lens is crazed, new housings are the long-term fix. Keeping a UV sealant on the lenses after washing helps slow future yellowing.

How should the Altezza’s headlights be aimed?

There are vertical and horizontal adjusters on the rear of each housing. Aim the lights on a level surface against a wall and set cutoff height and lateral position to ADR/NZTA guidance, or have a workshop use a beam-setter. Correct aim maximises seeing distance without dazzling oncoming traffic and is commonly checked at WoF.
