2024 Honda CR-V Bulb Sizes (Headlight, Tail, Fog)

Quick reference

The 2024 Honda CR-V, especially in its higher trim levels, comes extensively equipped with LED lighting from the factory. This offers superior illumination and longevity compared to traditional halogen bulbs. However, some lower trim levels, particularly the LX, may still utilize halogen bulbs in certain applications, and even higher trims might have a few halogen outliers.

For most CR-V models in 2024, the low beam and high beam headlights are integrated LED units. This means there isn't a replaceable bulb in the traditional sense; if the LED unit fails, the entire assembly typically needs to be replaced. These factory LED headlights provide excellent light output and a crisp, modern appearance.

Fog lights are predominantly LED on the 2024 CR-V, especially on Sport, EX-L, Sport-L, and Touring trims. However, some base LX models might still feature H8 halogen fog light bulbs. It's always a good idea to confirm your specific trim level.

Daytime Running Lights (DRL) are also factory LED on all 2024 CR-V models, often integrated into the headlight assembly design, providing a distinctive signature.

Front turn signals can vary. While many 2024 CR-V trims feature LED front turn signals, some models, particularly the LX and EX, may still utilize a WY21W halogen bulb. Rear turn signals are consistently LED across all trims for the 2024 model year.

Both brake lights and tail lights are integrated LED units on the 2024 Honda CR-V, delivering bright, fast-illuminating signals for enhanced safety and a contemporary look.

The reverse lights on all 2024 CR-V trims typically use a W16W halogen bulb, providing clear white light for backing up. Similarly, the license plate lights use a W5W halogen bulb.

Side marker lights are integrated into the headlight assembly (front) or tail light assembly (rear). The front side markers commonly utilize a W5W halogen bulb, while the rear side markers are part of the LED tail light unit and not individually replaceable.

Inside the cabin, both the dome light and map lights are factory LED on the 2024 CR-V, offering bright and efficient interior illumination.

LED vs Halogen Upgrade Considerations

For any remaining halogen bulbs on your 2024 Honda CR-V, upgrading to aftermarket LED bulbs can offer significant benefits, including brighter light, a longer lifespan, and a more modern aesthetic. However, there are a few important considerations:

• CANBUS Errors: Modern vehicles like the 2024 CR-V utilize a CANBUS (Controller Area Network Bus) system to monitor various electrical components, including lighting. Halogen bulbs draw more power than LED bulbs. When you replace a halogen bulb with an LED, the lower power draw can sometimes be interpreted by the CANBUS system as a "bulb out" error, leading to flickering or warning messages on your dashboard. To circumvent this, you may need to use CANBUS-compatible LED bulbs or install load resistors.
• Adapter/Resistors Needed: Load resistors essentially mimic the power draw of a halogen bulb, tricking the CANBUS system into recognizing the LED as a standard bulb. Some aftermarket LED kits come with integrated resistors, while others require separate installation. For turn signals, special LED flash relays might also be necessary to prevent hyper-flashing.
• Fitment: Always ensure that any aftermarket LED bulb you purchase is designed to fit your CR-V's specific housing. While the base socket might be the same, the LED bulb's larger heatsink or fan (common in high-power LEDs) might interfere with lens covers or tight spaces.

How to Replace Each Bulb

• Low Beam/High Beam Headlight: As these are factory LED units, direct bulb replacement is generally not possible. If there's a fault, professional diagnosis and likely replacement of the entire headlight assembly is required.
• Fog Light (Halogen H8): Access typically involves removing clips or screws from the fender liner underneath the front bumper. Reach in, twist the bulb counter-clockwise, and pull it out. Insert the new bulb and twist clockwise to secure.
• Front Turn Signal (Halogen WY21W): Access is usually from the engine bay, behind the headlight assembly. Twist the bulb socket counter-clockwise to remove, pull out the old bulb, and insert the new one.
• Reverse Light (Halogen W16W): Access is usually from inside the trunk, behind the tail light assembly. Remove the trim panel to expose the back of the tail light. Twist the bulb socket and replace the bulb.
• License Plate Light (Halogen W5W): These are usually accessed by carefully prying off the clear lens cover from the outside, often with a small plastic trim tool. Be gentle to avoid breaking the clips.
• Front Side Marker (Halogen W5W): Similar to the license plate light, these often require prying off a small lens or reaching from behind the headlight assembly.
• Dome Light / Map Light (LED): Generally, LED interior lights are sealed units. If equipped with a replaceable LED "board" style, gentle prying of the lens cover with a plastic tool will reveal it. If it's a specific "bulb" style in a housing, twist the socket first.

Common Lighting Issues for This Generation

While the 2024 Honda CR-V primarily utilizes durable LED lighting, which minimizes common bulb-out issues, a few things to be aware of include:

• LED Module Failure: Though rare, integrated LED modules can fail. This typically results in a partial or complete loss of light from an entire assembly (e.g., half of a DRL strip or an entire headlight). This usually necessitates replacement of the complete unit, which can be costly.
• Wiring/Connection Issues: Even with LED lighting, wiring harnesses or connectors can sometimes experience issues, leading to intermittent or complete light failure. This often requires professional diagnosis.
• CANBUS Errors with Aftermarket LEDs: As mentioned, if you replace any remaining halogen bulbs with non-CANBUS compatible LEDs without load resistors, you may experience "bulb out" warnings or rapid flashing (hyper-flashing) for turn signals.
• Condensation in Headlights/Taillights: While not a bulb issue, condensation can sometimes build up inside sealed headlight or taillight units. Minor condensation is often considered normal, but significant amounts or "puddling" could indicate a seal issue.
