2024 Toyota Camry Bulb Sizes (Headlight, Tail, Fog)

Quick reference

The 2024 Toyota Camry, a popular sedan known for its reliability and modern features, offers a mix of halogen and LED lighting across its various trim levels. Understanding the specific bulb sizes and types for your Camry is crucial for maintenance, repairs, and upgrade considerations. While many higher trims and optional packages come equipped with advanced LED lighting from the factory, many entry and mid-level trims still utilize traditional halogen bulbs for certain functions.

For example, lower trim Camrys often feature H11 halogen bulbs for low beams and 9005 halogens for high beams. These are common and easily replaceable. However, many trims, especially the XSE and XLE, come with integrated LED headlights that are not designed for user-replacement of individual bulbs. The same distinction applies to fog lights, where some models use H16 (Type 2) halogen bulbs, while others have integrated LED units. The Daytime Running Lights (DRLs) are almost universally integrated LED strips in the 2024 Camry, offering a distinctive modern look that is not user-serviceable.

Turn signals, brake lights, tail lights, and reverse lights see a similar split. While many models still use incandescent bulbs like the 7440A for front and rear turn signals, 7443 for brake and tail lights, and 7440 for reverse lights, higher trims often upgrade to full LED assemblies for these functions. License plate lights (168 or similar) and side marker lights (194) are typically incandescent, although LED upgrades are common and simple.

Interior lighting, such as the dome and map lights, is largely LED in most 2024 Camry trims, providing a brighter and more modern cabin ambiance. The dome light typically uses a 31mm fuse-style LED, while map lights frequently use a 194-type LED bulb.

LED vs halogen upgrade considerations

Upgrading your 2024 Toyota Camry's halogen bulbs to LED can significantly improve visibility and modernize its appearance. However, there are several "gotchas" to be aware of. The most common issue is CANBUS errors. The Camry's onboard computer (CANBUS system) monitors bulb resistance. Halogen bulbs draw more power and have higher resistance than LEDs. When you install an LED, the lower resistance can trick the CANBUS system into thinking the bulb is out, triggering a "bulb out" warning light on your dashboard. To circumvent this, you'll often need CANBUS-compatible LED bulbs or load resistors (decoders). These resistors mimic the electrical load of a halogen bulb, preventing error messages.

Another consideration is adapters. While some LED bulbs are designed for direct plug-and-play replacement, others may require specific adapters or retainers to properly fit into the Camry's headlight housing. The beam pattern can also be affected; poorly designed LED bulbs can scatter light, creating glare for oncoming drivers even if they are bright. Opt for LED bulbs with adjustable collars or those specifically designed to replicate the halogen filament position for optimal beam focus.

For turn signals, if you convert from incandescent to LED, you will likely encounter hyper-flashing. This occurs because the reduced resistance of the LED bulb causes the turn signal relay to flash much faster, again indicating to the car that a bulb is out. Load resistors are also necessary here to correct the flash rate.

How to replace each bulb

Replacing bulbs on your 2024 Camry generally involves a few common steps, though specific access varies by location:

• Low Beam/High Beam (Halogen): Access is usually from under the hood. Locate the back of the headlight assembly. Twist and pull the old bulb out, unplug the connector, and install the new bulb in reverse. Be careful not to touch the glass of new halogen bulbs.
• Fog Light: Often accessible from underneath the car by turning the wheel and/or removing a few clips from the fender liner, or sometimes from the front grille area. Twist to remove the old bulb.
• Front Turn Signal: Typically accessed from under the hood, similar to the headlights, or occasionally by partially removing the fender liner.
• Rear Turn Signal, Brake Light, Tail Light, Reverse Light: Access is generally through the trunk. You'll need to remove a few trim panel clips or screws to expose the back of the tail light assembly. The bulbs usually twist out of their sockets.
• License Plate Light: A small screwdriver or trim removal tool is usually needed to carefully pry out the clear plastic lens covering the bulb, often from the outside near the license plate.
• Side Marker Light: These are often small, push-in fixtures on the fender. Access might be external with a trim tool, or from behind the fender liner.
• Dome/Map Lights: Utilize a plastic pry tool to gently unclip the lens cover. The bulbs are usually either a wedge-base type (194) or a fuse-style LED component that pops out.

Always consult your owner's manual for specific diagrams and instructions relevant to your Camry's trim level, as some procedures can differ slightly.

Common lighting issues for this generation

For the current generation of the Toyota Camry, common lighting issues are relatively few, reflecting Toyota's reputation for reliability. However, here are a few you might encounter:

• Premature Halogen Bulb Burnout: While not exclusive to the Camry, halogen bulbs, especially high beams and fog lights, can occasionally burn out sooner than expected. This can be exacerbated by vibrations or frequent exposure to moisture if seals are compromised.
• Integrated LED Module Failure: For trims with factory-installed LED headlights, DRLs, or tail lights, if a module fails, it often requires replacing the entire headlight or tail light assembly, which can be a costly repair. Unlike halogen bulbs, individual LEDs within these units are generally not replaceable. This is a rare occurrence but worth noting.
• "Bulb Out" Warnings After LED Upgrades: As mentioned, if you upgrade incandescent bulbs to aftermarket LEDs without proper CANBUS decoders or load resistors, you will almost certainly trigger "bulb out" warning lights on your dashboard.
• Condensation in Light Assemblies: On occasion, owners might notice condensation within the headlight or tail light assemblies. This can sometimes clear up on its own but can also indicate a compromised seal, potentially leading to premature bulb failure or electronics issues. If persistent, it might warrant inspection.
• Rear Tail Light or Brake Light Discrepancies: Less common, but sometimes one side will appear dimmer or fail independently due to wiring issues or a faulty bulb (on incandescent setups).
