Bulb numbers by function
These are the standard halogen bulb sizes used by most 2006 Priuses with conventional headlights. Always verify by inspecting the existing bulb or consulting the manual if you’re unsure.

Notes and caveats
Regional variations, trim levels, or vehicles equipped with HID or LED headlights can change the required bulb types. If your Prius has HID/LED headlights, the bulbs will be different and not H11/9005. Always verify with the owner’s manual or by inspecting the current bulbs.
Buying tips and compatibility
When shopping for replacements, consider these guidelines to ensure you pick the right parts and stay compliant with local regulations.
- H11 low-beam bulbs: standard 12V halogen, typically 55W; verify the exact variant from your current bulb or manual.
- 9005 high-beam bulbs: standard 12V halogen, typically 65W.
If there’s any doubt, consult Toyota’s official parts diagrams or your dealership to confirm the exact bulb numbers for your specific VIN and trim level.
Summary
The typical headlight setup for a 2006 Prius uses H11 for the low beams and 9005 for the high beams. Always double-check with your owner’s manual or by checking the bulbs themselves, as regional differences or optional equipment can alter the correct bulb type. Consider professional help for any HID/LED upgrades beyond stock specifications.
