The 2010 Honda CR-V generally uses standard halogen bulbs, with the most common starting point being H11 for low-beam headlights, 9005 for high-beam headlights, and H11 for fog lights (if your trim has fogs). Other bulb sizes vary by trim level and market, so it’s best to verify against your owner's manual or by inspecting the bulbs in use on your specific vehicle.
In this guide, we break down typical bulb sizes by location (headlights, rear lights, license plate, and interior) and explain how to confirm the exact size for your trim. The information aims to help you identify replacements quickly while noting where variations may occur.
Headlights and fog lights
Headlight bulb sizes can differ by trim and whether your CR-V uses reflector or projector housings. Here are the sizes that are commonly found on the 2010 CR-V.
- Low-beam headlights: H11
- High-beam headlights: 9005 (HB3)
- Front fog lights (if equipped): H11
Note: Some markets or trims may not include fog lights, and there can be variations in the exact bulb type depending on the assembly. Always verify with the exact bulb inside your headlight housing or the owner's manual.
Rear lighting (taillights, brake, turn, and backup)
The rear lighting cluster on the 2010 CR-V uses multi-function bulbs, and sizes can vary by market or trim. Here are the sizes you’re likely to encounter.
- Tail/brake/turn signal bulbs: often 3157 (dual-filament) or a close equivalent such as 3156 in some markets
- Backup (reverse) bulbs: typically 921
- Rear side/marker lights: sizes can vary (some markets use 194 or 168 for certain marker elements)
Because rear light assemblies differ by region, model year tweaks, or optional packages, confirm by removing the lens or checking the current bulb part number printed on the bulb itself.
License plate and interior lights
Smaller bulbs for plate and interior lighting follow common wedge or festoon formats. Here are the typical candidates you’ll encounter.
- License plate lights: 194 wedge bulbs (some markets use 168)
- Interior dome/map lights: 194 or 168 depending on the lamp assembly and market
If you’re replacing these, you’ll often be able to confirm by inspecting the bulb in place or by consulting the owner’s manual for the exact part number used on your vehicle.
How to verify the exact bulb size for your car
Because bulb sizes can vary by trim level, market, and optional equipment, use these steps to confirm the precise size for your CR-V.
- Check the owner’s manual under the Lighting section for bulb sizes by location.
- Inspect the existing bulb: remove it and note the part number printed on the base.
- Look at the bulb housing or lens label for a size code (often printed near the socket).
- If in doubt, bring the old bulb to an auto parts store or search the vehicle’s VIN-based parts database online to verify compatibility.
Following these steps will help ensure you purchase the correct bulb on your first attempt, preventing fit issues or the need for returns.
Summary
For a 2010 Honda CR-V, start with H11 for low-beam headlights, 9005 for high-beam headlights, and H11 for fog lights if equipped. Rear lighting commonly uses 3157 for tail/brake and 921 for backup, with license plate and interior lights often in the 194 or 168 family. Always verify against your specific trim and market by checking the owner’s manual or inspecting the current bulbs, as sizes can vary.
