Parts for your 2006 Toyota Highlander-Tail lights

2006 Toyota Highlander tail-lights (also known as Kluger in AU/NZ)

Tail-lights are absolutely fitted and relevant on the 2006 Toyota Highlander. Technical sources confirm this: Toyota’s Owner’s Manual for the 2006 Highlander details “rear combination light” bulbs and access, Toyota Repair Manual procedures cover removal and installation of the rear combination lamp assemblies, Toyota’s Electronic Parts Catalogue lists the assemblies (e.g., RH 81550‑48xxx / LH 81560‑48xxx). On top of that, lighting is mandated by FMVSS 108 (US), ADR 13/00 and 49/00 (Australia), and the NZ Land Transport Rule: Vehicle Lighting 2004—so this model must have functioning tail-lamps from factory.

On this Highlander/Kluger, the tail-lights sit high on the rear quarters and in the liftgate, combining tail, stop, indicator, and reverse functions for clear visibility. Their job is simple but vital: show the vehicle’s width and presence at night or in poor weather, light up brighter under braking, and indicate turns—keeping everyone behind in the picture.

For routine servicing, it’s smart to give the rear lamps a quick once-over. A wipe with a mild car wash solution and soft cloth keeps the lenses bright. If there’s moisture fogging inside, the housing seal may be compromised—worth fixing before it cooks the bulb holder or corrodes contacts. With the tailgate open, bulb replacement is straightforward via the inner trim access, twist the bulb holders anti-clockwise, swap the globes, and refit firmly. Common fits are dual‑filament 7443 for stop/tail, 7440 for indicators, and 921 for reverse, but always match what the manual specifies for the exact variant.

If a lens is cracked or the reflector is dull, replacing the whole rear combination lamp assembly restores output and keeps the vehicle legal. When refitting, check the foam gasket so rain stays out, and snug the mounting bolts without over-tightening. Considering an LED upgrade? Use ADR/UNECE‑compliant lamps or assemblies designed for this model to avoid glare, hyper‑flash, or roadworthy issues.

• Check operation: tail (park), brake, indicators, and reverse, ideally with a mate watching.
• Replace bulbs in pairs so brightness and colour match left to right.
• Keep spare bulbs in the boot for road trips and WOF/rego checks.

Popular questions about 2006 Toyota Highlander tail-lights

What bulb types does it use?
Most 2006 Highlanders use 7443 dual‑filament globes for stop/tail, 7440 for rear indicators, and 921 for reverse. Trims and markets can vary, so cross‑check the owner’s manual or the part number on the existing bulb before buying.

How can someone tell the tail-light assembly needs replacing rather than just a bulb?
If multiple functions in one corner are out, there’s water inside the lens, the lens is cracked, or the reflector looks burnt or cloudy, the assembly is likely the culprit. Persistent blown bulbs or corroded sockets also point to a failing housing or seal.

Are LED replacements legal in Australia and New Zealand?
They can be—provided the LED bulbs or complete lamp assemblies are ADR/UNECE compliant and the vehicle still meets its lighting requirements. Non‑compliant retrofits may fail a WOF/roadworthy and can dazzle other drivers. Use approved components and ensure indicators flash at the correct rate.
