A small wedge-base bulb (commonly W5W/194) or an LED replacement module is typically used for the license plate light on 2018 Toyotas. Some trims may use an integrated LED housing, which requires replacing the entire unit. Check your specific model to confirm.
Across the 2018 Toyota lineup, license plate illumination is generally straightforward to handle, but the exact type can vary by model and trim. This article explains how to identify your setup, what to buy, and how to replace it safely.
Common license plate light options on 2018 Toyota models
Before you shop, note the two primary configurations you’re likely to encounter:
- Replaceable incandescent wedge-base bulbs, often labeled W5W or 194 (some models use the 168 variant). These bulbs plug into a standard license plate lamp socket and can be swapped individually.
- LED replacement bulbs or LED module assemblies designed to fit the license plate housing. In some trims, the LED module is integrated, and the entire lamp assembly must be replaced if you want to upgrade or repair.
In short, most 2018 Toyotas use either a replaceable bulb or an LED module; confirm your specific setup before purchasing replacements.
How to identify which type your car uses
Use these steps to determine whether your license plate light uses a bulb you can replace or an LED module.
- Inspect the light fixture behind the license plate area: a small bulb with a wedge base indicates a replaceable bulb; a flat LED board or sealed unit indicates an LED module.
- Consult the owner’s manual or dealership parts diagram for the exact bulb type or lamp assembly described for your model and trim.
- Remove the lens carefully to read markings on the bulb or socket (look for codes like W5W/194 or an LED part number).
Knowing whether you have a bulb-based setup or an LED module will guide you to the correct purchase and replacement method.
Replacing or upgrading the license plate light
If you have a replaceable bulb, you can buy a W5W/194 or equivalent wedge-base bulb and swap it in quickly. If you have an LED module, you’ll typically need to replace the entire lamp assembly or the LED module itself, depending on the design. Always disconnect the battery before working on electrical components and dispose of old bulbs properly.
Summary: For a 2018 Toyota, license plate illumination usually uses a wedge-base bulb (commonly W5W/194 or similar) or an LED module; confirm via manual or by inspecting the fixture. Replacing is straightforward for bulbs, while LED modules may require replacing the whole unit.
