2019 Honda CR-V Bulb Sizes (Headlight, Tail, Fog)

Quick reference

The 2019 Honda CR-V, a popular compact SUV known for its reliability and practicality, came with various lighting configurations depending on the trim level. Understanding the specific bulb sizes and types is crucial for proper maintenance and upgrades. This guide provides a comprehensive breakdown of all common bulb sizes for your 2019 CR-V.

For many CR-V owners, the most significant difference in lighting will be found in the headlights. Lower trim levels (LX, EX, EX-L) typically came equipped with halogen H11 bulbs for the low beams and 9005 bulbs for the high beams. Higher trims (Touring) often featured integrated LED low beams, which are not user-replaceable as individual bulbs. These LED headlights offer superior illumination and a distinct look. Fog lights, when present, generally use H8 halogen bulbs across all trims.

The DRLs (Daytime Running Lights) on the 2019 CR-V utilize the WY21W halogen bulb, which also serves as the front turn signal. This is a common setup designed for efficiency. The rear turn signals feature a 7440A halogen bulb. For braking, the brake lights use a 7443 halogen bulb, which is a dual-filament bulb that also handles the brighter brake function. The tail lights themselves are often integrated LED units on most trims and are not typically serviceable by replacing individual bulbs. The reverse lights are standard 7440 halogen bulbs.

Moving to smaller exterior lights, the license plate lights use 168 halogen bulbs, and the front side markers are typically 194 halogen bulbs. Similar to the tail lights, the rear side markers are often integrated LED units.

Inside the cabin, the dome light commonly uses a DE3175 festoon bulb, while the map lights utilize 175 wedge bulbs. These interior lights are relatively straightforward to replace and can be a popular target for LED upgrades.

LED vs halogen upgrade considerations

Upgrading from halogen to LED bulbs in your 2019 Honda CR-V can significantly improve brightness, longevity, and give your vehicle a more modern aesthetic. However, there are several key factors to consider:

• CANBUS Errors: Modern vehicles like the CR-V use a CANBUS (Controller Area Network Bus) system to monitor electrical components, including lighting. When you replace a halogen bulb with an LED, the lower power draw of the LED can sometimes trick the CANBUS system into thinking the bulb is out, triggering a "bulb out" warning on your dashboard. To circumvent this, many aftermarket LED bulbs come with built-in CANBUS decoders, or you may need to purchase separate load resistors (adapters) to simulate the power draw of the original halogen bulb. It's crucial to choose LED bulbs specifically designed as "CANBUS error-free" for your CR-V to avoid these issues.

• Adapters Needed: Beyond CANBUS decoders, some LED bulbs, especially for headlights, may require specific mounting adapters or retainer clips to fit correctly into the CR-V's headlight housing. The base of an LED bulb can sometimes be bulkier than a halogen bulb, so ensure any aftermarket LED you purchase is compatible with your vehicle's specific housing type. Heat sinks on LED bulbs can also affect fitment and require adequate space within the housing.

• Beam Pattern and Glare: High-quality LED headlight bulbs are designed to replicate the beam pattern of their halogen counterparts. However, poorly designed or installed LED bulbs can scatter light excessively, creating glare for oncoming drivers and reducing your effective visibility. Look for LED bulbs with adjustable collars or those specifically designed to work well in reflector or projector housings (depending on your CR-V's headlight type).

How to replace each bulb

• Low Beam/High Beam: Access to the headlight bulbs typically involves removing a plastic cover or shield within the engine bay, then twisting and pulling the bulb out. For the high beam, it
