1999 Toyota Echo/Yaris Headlights

Headlights are absolutely fitted and relevant on the 1999 Toyota Echo (XP10), also sold as the Yaris. Toyota’s owner’s and workshop manuals specify halogen headlamps for this model, and road-legal lighting is mandated by Australian Design Rules (notably ADR 13/00 and ADR 46/00) and by New Zealand’s Vehicle Lighting Rule and Warrant of Fitness requirements. So yes—this Echo/Yaris runs factory headlamps and needs them in good nick for both safety and compliance.

The headlights on a ’99 Echo/Yaris do the heavy lifting for night driving and poor weather visibility, with low beam for everyday use and high beam for open-road illumination. They also help other drivers spot the car, day and night. Most examples use a dual‑filament H4 12V 60/55W halogen globe, giving both dipped and main beam from the one bulb. Clear, well‑aimed lamps keep the beam on the road where it belongs and stop glare for oncoming traffic.

As part of regular servicing, it’s worth giving the headlights a quick once‑over every six months. Look for cloudy or yellowed lenses (common with polycarbonate over time), moisture inside the housing, cracked tabs, and any wiring or connector heat damage. If the beam seems weak or patchy, the globe may be fading—halogens dim before they fail. Replace bulbs in pairs so colour and brightness match, and stick to the specified wattage to avoid melting sockets or reflectors. After any front‑end work or bulb change, check the aim, misalignment can fail a WOF/reg inspection and makes night drives frustrating.

Swapping the bulb is straightforward: open the bonnet, unplug the three‑pin connector, peel back the rubber dust boot, release the spring clip, and remove the H4 globe. Avoid touching the glass—skin oils shorten bulb life. Refit in reverse, ensuring the locator tabs seat properly, then test low and high beam. If a light is still out, check the relevant fuse and the headlight relay.

• Restore hazy lenses with a proper headlight restoration kit and UV sealant.
• Keep away from over‑wattage or cheap “blue” bulbs, choose quality ADR/NZTA‑compliant halogens.
• If water gets in, replace the rear boot and inspect the housing seals to prevent future fogging.

Popular questions

What headlight bulb does a 1999 Toyota Echo/Yaris use?

Most 1999 Echo/Yaris models use an H4 12V 60/55W halogen bulb for combined low and high beam, plus small T10 wedge parkers. Always confirm against the glovebox manual or the existing bulb markings, as market variations exist.

How can they fix cloudy or yellowed headlights?

Use a headlight restoration kit that sands, polishes, and applies a UV clear coat to the polycarbonate lens. If lenses are cracked or the reflectors are dull, a replacement assembly is the lasting fix. Keeping a UV protectant on the lenses slows future yellowing.

How should the headlights be aimed on the Echo/Yaris?

Park on level ground about five metres from a wall, measure beam height at the wall to match the headlight centre height, and adjust using the housing screws. For perfect results and compliance with ADR/NZ specs, a workshop beam setter or a WOF/rego inspection station can dial it in precisely.
