Parts for your 2020 Subaru Outback-Tail lights

2020 Subaru Outback tail-lights: what they do and how to look after them

Tail-lights are absolutely fitted to the 2020 Subaru Outback. That’s documented in the 2020 Outback Owner’s Manual and Subaru service information, which describe the rear combination lamps (including tail-lights/rear position lamps). They’re also required for road use under Australian Design Rules (ADR 13/00 installation of lighting, relevant ECE standards such as R7/R48) and New Zealand’s Land Transport Rule: Vehicle Lighting 2004. So yes—tail-lights are relevant, standard, and essential on this model.

On the 2020 Outback, the tail-lights form part of the rear combination assembly, giving a clear red rear position light signature whenever the headlights or auto lights are on. Their job is simple but critical: make the vehicle visible from behind in low light, rain, fog and at night, helping other road users judge distance and width. Many 2020 Outback variants use LED tail-lights for crisp illumination, low current draw and long life, while indicators and reverse lamps may vary by market.

As part of routine servicing, tail-lights deserve a quick once-over. A tidy approach for Outback owners looks like this:

• Function check: Once a month, switch on the park/headlights and walk around the car. Confirm both tail-lights glow evenly. Ask a mate to check while you tap the lamp gently—flicker hints at a loose connector.
• Lens care: Wipe lenses with a soft cloth and mild car-wash solution. Avoid harsh solvents that can craze the plastic.
• Water ingress: Look for condensation or water pooling. Any moisture can corrode connectors—if present, the lamp seal or housing may need replacing.
• Electrical basics: If both tail-lights are out, check the relevant “TAIL/ILLUM” fuse and headlight switch setting. If only one side is out, suspect the lamp unit or its connector/earth.
• LED vs bulb: Many Outbacks use sealed LED modules for tail-lights, if an LED segment fails or dims, the remedy is typically replacing the lamp assembly. If your market/trim uses a bulb for the tail function, match the exact type and wattage, and only use ADR-compliant replacements.

Replacing the rear lamp assembly is straightforward: open the tailgate, remove the boot-side trim access, undo the mounting bolts, slide the lamp rearwards off its locator pins, unplug the connector, swap in the new unit, then refit and test. Don’t overtighten bolts, and keep the body seal clean to prevent leaks. If you find damaged wiring, persistent moisture, or trailer-wiring quirks, a licenced auto electrician or Subaru dealer is the smartest move. Keeping the tail-lights bright and healthy helps with WOF/rego checks and makes night drives far less stressful for everyone behind.

Do 2020 Outback tail-lights use LEDs?

Most 2020 Subaru Outback variants feature LED tail-lights integrated into the rear combination lamps. LEDs offer quick response, a clean light signature and long service life. Depending on market and trim, indicators or other rear bulbs may still be incandescent. If a tail-light LED fails, the usual fix is replacing the lamp assembly rather than a bulb.

How does someone replace a tail-light on a 2020 Outback?

Open the tailgate, pop off the boot-side access trim, remove the lamp’s mounting bolts, and slide the unit straight back off its guide pins. Unplug the connector, fit the new lamp, then refit and test. If the vehicle uses LED tails, it’ll be a full assembly swap. Always match genuine spec, check the seal, and avoid overtightening to prevent cracking the housing.

Why would a 2020 Outback tail-light work intermittently?

Common culprits include a loose connector, a poor earth, moisture inside the housing, or a chafed wire—especially if a towbar or trailer module has been fitted. If both sides play up, look to the fuse or lighting switch circuit. Any signs of water ingress or corrosion warrant replacing the lamp and cleaning the connector, then testing with a multimeter.
