A customer says:

“I have a 2022 Toyota Highlander. Which retrofit kit should I order?”

The model year gives us a starting point.

It does not automatically answer the question.

Royalin currently has two very different documented retrofit references for the 2022 Toyota Highlander:

• a conventional projector bracket retrofit;
• a full three-projector matrix retrofit.

Both belong to the same vehicle year.

But internally, they solve very different retrofit problems.

That is why the right question is not simply:

“Projector or matrix?”

It is:

“Which headlight configuration do you have, and which documented retrofit architecture matches it?”

Route 1: Conventional Projector Bracket Retrofit

The 2022 Toyota Highlander projector bracket retrofit case follows the more conventional of the two architectures.

The documented setup uses:

• a vehicle-specific projector bracket;
• rear-mounted projector installation;
• supplied clips;
• trim bezel preparation;
• rear-clearance checks;
• low/high-beam polarity verification.

The basic objective is to replace or upgrade the projector while working around the original headlight structure.

That makes the bracket and projector dimensions especially important.

Rear-Mounted Projector Fitment Changes the Clearance Check

In this setup, the projector mounts from the rear.

That means the installer needs to consider what happens behind the mounting surface.

Important dimensions include:

• projector rear body length;
• fan or heat-sink depth;
• connector location;
• wire routing;
• rear housing clearance.

A projector can match the mounting holes and still be unsuitable if the rear body is too long.

This is why “same lens diameter” does not guarantee the same fitment.

Trim Bezel Preparation Is Part of the Job

The documented projector-bracket route also requires preparation of the surrounding trim bezel.

This should be controlled rather than treated as broad cutting.

The goal is to create the required clearance for the projector while preserving:

• original appearance;
• trim strength;
• projector alignment;
• surrounding headlight structure.

Test fitting is important before final trimming.

Once material is removed, it cannot easily be put back.

Route 2: Full Matrix Retrofit

The 2022 Toyota Highlander full matrix retrofit case is a very different system.

Instead of installing one replacement projector, the retrofit uses a dedicated matrix carrier with three projector positions.

The documented structure includes compact projector formats in approximately the 1.5–1.8 inch range, depending on position and configuration.

This changes the job from:

fitting a projector to the original mounting position

to:

building a controlled multi-projector system inside the original headlamp.

That is a much bigger architectural change.

A Matrix Carrier Has to Control Multiple Optical Positions

With a single projector, the installer mainly needs to control one optical center.

With three projectors, the relationship between all projector positions becomes important.

The matrix carrier needs to control:

• horizontal spacing;
• vertical position;
• projector angle;
• front depth;
• rear clearance;
• trim relationship.

A small error in one position can affect the visual alignment of the entire group.

That is why a full matrix conversion should be treated as a complete carrier system rather than three independent projector installations.

The Inner Projector Position Needs Extra Attention

The documented full matrix setup includes a specific inner-projector positioning requirement.

Its angle and relationship to the surrounding structure need to be checked during assembly.

This is important because compact projectors do not automatically sit correctly just because they physically fit inside the carrier.

The installer still needs to verify:

• optical orientation;
• lens position;
• carrier alignment;
• surrounding shroud clearance.

A matrix retrofit is more sensitive to small positioning errors because the projectors are visually grouped together.

Shroud Modification Is More Important in the Matrix Route

The full matrix retrofit also requires controlled modification of the original shroud area.

Again, the objective is not to remove as much material as possible.

It is to remove only what is necessary for the matrix carrier and projectors to sit correctly.

The original surrounding structure still matters because it affects:

• finished appearance;
• projector visibility;
• clearance;
• internal rigidity.

The final result should look integrated into the headlight rather than added as an afterthought.

Rear Cover Clearance Matters in Both Systems

Even though the two architectures are different, they share one important issue:

available space inside the headlight still matters.

For the conventional projector setup, rear body depth can affect the housing directly.

For the full matrix system, three projector bodies, their mounting structure and associated wiring all have to fit inside the available envelope.

Before closing the lamp, the installer should check:

• projector-to-housing clearance;
• rear-cover clearance;
• wiring paths;
• fan or heat-sink space;
• adjuster movement.

A retrofit is not complete simply because the projector carrier bolts in.

The entire assembly still needs enough room to operate and close correctly.

Projector Bracket and Full Matrix Are Not Upgrade Levels

It would be easy to describe the matrix system as the “higher version” of the projector-bracket retrofit.

That is not the best way to understand these two cases.

They are different architectures.

Conventional projector bracket

Focuses on:

• one main replacement projector;
• vehicle-specific bracket fitment;
• trim bezel preparation;
• rear-mounted projector clearance;
• low/high-beam verification.

Full matrix

Focuses on:

• three projector positions;
• dedicated carrier geometry;
• compact projector sizing;
• shroud modification;
• multi-projector alignment;
• rear-cover clearance.

One is not automatically the correct replacement for the other.

A Simple Comparison

Electrical Functions Still Need to Be Verified

Regardless of which architecture is used, electrical connections should not be assumed.

For the conventional projector-bracket reference, low/high-beam polarity needs to be checked.

For a matrix conversion, the installer also needs to make sure the projector functions are connected according to the intended optical layout.

Actual circuit verification is safer than relying only on:

• wire color;
• connector appearance;
• another vehicle's wiring photo.

Replacement headlights, regional specifications or previous repairs can change the situation.

The Housing Seal Also Matters

The documented 2022 Highlander projector case uses an OEM butyl-sealed housing.

That affects how the lamp is opened and resealed.

The sealing channel should be preserved during disassembly.

Before the headlamp is closed again, check:

• projector security;
• carrier security;
• trim clearance;
• rear clearance;
• low beam;
• high beam;
• matrix functions where applicable;
• final beam aim.

The optical retrofit and the housing work should be treated as one complete job.

What Should a Shop Confirm Before Ordering?

For a 2022 Highlander retrofit inquiry, useful information includes:

1. Vehicle year
2. Market or country
3. Full front vehicle photo
4. Close headlight photo
5. Rear housing photo
6. Headlamp label
7. OEM or aftermarket housing
8. Internal headlight photo if available
9. Current projector / reflector layout
10. Intended retrofit architecture
11. Intended projector model and dimensions

That last point is especially important.

The supplier should know whether the customer is trying to build:

• the documented conventional projector configuration;
• the documented full matrix configuration;
• or another custom setup.

Same Year Does Not Mean the Same Retrofit Solution

The two 2022 Highlander cases make one point very clearly:

model year alone does not define the retrofit.

One documented solution uses a conventional rear-mounted projector bracket.

The other uses a three-projector matrix carrier.

The hardware, clearance requirements, trim work and alignment logic are different.

For retrofit shops and distributors, the practical rule is:

identify the actual headlight and intended architecture before selecting the kit.

That is much more reliable than treating every “2022 Highlander” inquiry as the same application.
