Parts for your 2016 Toyota Land cruiser-Interior bulbs

2016 Toyota Land Cruiser interior bulbs — what they do and how to look after them

Referencing technical sources including the Toyota Owner’s Manual for the 2016 Land Cruiser (J200), Toyota’s Repair Manual (Body Electrical – Interior Lighting), and the Toyota Electronic Parts Catalogue (URJ202/VDJ200, 08/2015-on), interior bulbs are absolutely relevant to this model. The vehicle is fitted with a mix of interior illumination lamps: many roof/map and cargo lights are factory LED modules on higher trims, while items like the vanity mirror, glove box and some door courtesy lights may be conventional replaceable bulbs depending on market and grade in Australia and New Zealand.

Inside a 2016 Land Cruiser, interior bulbs do the everyday heavy lifting—lighting the cabin when hopping in at night, giving map-reading light up front, brightening the second and third rows for the kids, and keeping the boot and glove box usable after dark. They also handle courtesy duties when doors open, and they gently fade thanks to the Body ECU, so things feel a bit more premium.

As part of regular servicing, it’s smart to check that every interior lamp operates on the DOOR and ON settings. Clean each lens with a soft microfibre cloth—dust and sunscreen film can dull the output. If multiple lamps don’t work, the ROOM/DOME fuse in the cabin junction block is the first stop before blaming the bulbs.

Replacement varies by trim. Many roof and cargo lamps are LED assemblies, if one fails, the complete lamp unit is replaced rather than a globe. Other positions typically use common sizes:

• Vanity mirror: festoon (often 29–31 mm)
• Glove box: T10/W5W wedge
• Door courtesy: T10/W5W wedge or LED module

Upgrading to quality LEDs where a bulb is used is popular. Pick non-polarity or note that LEDs have polarity, if it doesn’t light, flip it. Stick to sensible brightness and a warm-to-neutral colour (around 4000–5000K) to match OEM and avoid glare. Avoid high-watt incandescent globes—heat can yellow lenses and mark trim.

Use a plastic trim tool to ease lenses off without scuffing the headlining or covers. Switch the lights off and keep the key out of the ignition, if working near side curtain airbag areas, be gentle with the trim. When replacing festoons, confirm the exact length (31 mm is common) so the contacts grip properly. For LED assemblies, confirm the lamp part number by VIN, as AU/NZ grades differ.

• What bulb sizes are used in a 2016 Land Cruiser’s interior?
  It depends on the trim and market. Many roof/map and cargo lamps are LED modules from factory, while vanity mirror and glove box globes are commonly a 29–31 mm festoon and a T10/W5W wedge. Door courtesy lamps may be either T10 bulbs or LED modules. The Toyota Owner’s Manual and EPC list the exact fitments for the specific VIN.
• Are the interior lights all LED from factory?
  On higher-spec AU/NZ models, most roof and cargo lights are LED. However, several positions—like the vanity mirror and glove box—often remain conventional bulbs. Where LEDs are used, they’re generally non-serviceable modules, so the complete lamp unit is replaced if it fails.
• Will interior lights drain the battery if left on?
  The Land Cruiser’s Body ECU provides an auto-off function that turns interior lights off after a period with the ignition off, helping prevent a flat battery. If lights stay on, check that a door isn’t slightly ajar and verify the DOOR/ON switch positions, persistent issues can point to a door switch or wiring fault.
