Parts for your 2016 Toyota Mark x-Tail lights

2016 Toyota Mark X tail-lights

Tail-lights are absolutely fitted to the 2016 Toyota Mark X. Technical sources including the Toyota Mark X Owner’s Manual (2016 JDM edition), the Toyota Electronic Parts Catalogue for the GRX130/133/135 series (listing “Rear Combination Lamp Assembly LH/RH”), and lighting regulations used in export markets (UNECE R48 and Australian Design Rule 13/00 for rear position lamps) all confirm the vehicle uses rear combination lamps — typically LED tails with integrated stop and indicator functions. So tail-lights are relevant, required, and part of every 2016 Mark X.

On a 2016 Mark X, the tail-lights do more than just glow red at night — they’re a key safety feature that makes the car visible from behind, marks out its width, and signals braking and turns. The facelifted GRX130 series commonly uses LED rear combination lamps for the tail and stop functions, delivering crisp light, fast response, and long service life. Indicators and reverse lights may be LED or incandescent depending on trim and market, but the assemblies are designed as complete left/right units, sealed against the weather.

As part of regular servicing, a quick lighting check is smart and takes seconds. With the park lamps on, confirm both tails are evenly bright and the colour is consistent. Press the brake, operate indicators and hazard lights, and pop it into reverse (with the park brake applied) to confirm all functions. If one side is dim, flickering, or out, the issue could be a blown globe (if fitted), a failed LED segment, moisture in the lens, a dirty earth, or a damaged connector.

• Common watch-outs: condensation inside the lens, cracked housings, damaged gaskets, corroded plugs, and blown fuses.
• Simple fixes: clean the connector pins, replace perished gaskets, and reseat the harness. For LED failures, the assembly usually needs replacement.
• Service interval tip: test the lights at every fuel fill or before WOF/RWC checks.

1. Open the boot and remove the trim clips to access the lamp mounting area.
2. Unplug the harness
