Parts for your 2015 Subaru Exiga-Tail lights

2015 Subaru Exiga tail-lights — what they do and how to look after them

Technical sources confirm tail-lights are absolutely fitted to, and required on, the 2015 Subaru Exiga. Subaru literature (2015 Exiga owner’s manual and service manual wiring diagrams for the rear combination light circuit) lists rear position/parking lamps, stop lamps, indicators and reverse lamps as part of the rear combination assemblies. Regional regulations that the Exiga is built to meet—such as Australian Design Rule 13/00 (installation of lighting) and the New Zealand Land Transport Rule: Vehicle Lighting 2004—also mandate rear position (tail) lamps on passenger vehicles. So yes, tail-lights are relevant, used and essential on this model.

On the 2015 Exiga, the tail-lights sit within the rear combination lamps. Their job is simple but critical: they make the vehicle visible from behind at night and in poor weather, and they share housing with the brake, indicator and reverse functions. Whether using conventional bulbs or LED elements (varies by trim and market), a healthy tail-light setup keeps night-time driving relaxed and roadworthy inspections hassle-free.

As part of normal servicing, it’s smart to check the tail-lights every few months, and before a WOF or rego check. Switch on the park lights and hazards, and have someone confirm both sides glow evenly. If a bulb’s out or looks dim, replace it promptly—running with a dud lamp can cop a defect, and it’s not great for safety.

• Replacement basics: open the tailgate, remove the trim access panel, twist out the bulb holder, and swap in the correct spec bulb. Avoid touching the glass with bare fingers—use gloves or a clean tissue.
• For LED-equipped variants: if an LED module fails, the usual remedy is replacing the lamp assembly rather than a bulb. Check the manual or a trusted parts supplier for the correct assembly.
• Keep it sealed: inspect the gasket and lens for cracks or moisture. Light condensation can be normal, pooling water isn’t—sort the seal before it cooks the electrics.
• Electrical checks: if both sides are out, check the relevant fuse and earth points. Trailer wiring add-ons are a common culprit for odd lighting faults.
• Use the right parts: stick to ADR/NZ-compliant bulbs and assemblies. Higher-wattage “hot” bulbs can haze the lens and melt holders.

A clean lens makes a difference too—wash with mild car shampoo and avoid harsh solvents that can craze the plastic. If the lamps are cloudy or cracked, replacing the pair keeps the rear end looking fresh and the light output even.

Popular questions about 2015 Subaru Exiga tail-lights

What bulb type does the Exiga use for the tail-light?
Many 2015 Exiga trims use dual‑filament bulbs for the tail/stop function and single‑filament bulbs for indicators and reverse, but exact specs vary by market and grade. The safest bet is to check the owner’s manual or the marking on the lamp holder, then match quality ADR/NZ‑compliant replacements.

Will a failed tail-light cause a WOF or rego issue?
Yes. A non‑working rear position lamp or stop lamp will typically lead to a failed WOF in New Zealand and can attract a defect or fail a roadworthy in Australia. It’s an easy fix—replace the bulb or lamp assembly before the inspection.

Why is there condensation in the tail-light, and is it bad?
A light mist on the inside after rain can be normal as the lamp “breathes” and usually clears when dry. Visible droplets or pooling water suggests a leaky seal or cracked lens—repair or replace the gasket or assembly to protect the wiring and maintain full brightness.
