Most 2011 Toyota Sienna models with standard headlights use H11 for low beams and 9005 for high beams; if your vehicle has factory HID headlights, the low-beam bulbs are D2S or D4S and the high beam may be a separate halogen bulb (often 9005). Always verify with the owner’s manual or the label on the headlight housing for your exact trim.
Halogen headlights (the most common configuration)
The bulbs for the typical halogen headlamps on the 2011 Sienna are listed below.
- Low beam: H11
- High beam: 9005 (HB3)
- Fog lights (if equipped): H11
In most trims with halogen headlights, this is the standard bulb setup. If your vehicle has a different headlamp configuration or aftermarket parts, double-check with the manual or parts diagrams for your exact build.
HID/Xenon headlights (factory or optional)
If your 2011 Sienna uses HID headlights, the bulbs differ from the halogen setup. The low-beam HID bulb type depends on the ballast your car uses, typically D2S or D4S, and the high beam is often a separate halogen bulb or an HID high-beam arrangement depending on the trim. Always verify the exact bulb type by checking the owner's manual or the label on the headlight ballast or housing.
- Low beam: D2S or D4S (depends on ballast and housing)
- High beam: typically a separate halogen bulb (commonly 9005) or a dedicated HID high-beam configuration depending on trim
Conclusion: If your Sienna has HID headlights, you’ll need to identify the ballast and bulb type for accurate replacement. When in doubt, consult the official diagrams or a Toyota parts specialist and replace bulbs in matched pairs when possible to maintain consistent color and brightness.
How to tell which system you have
Inspect the headlight assembly and the wiring: HID systems include a ballast and distinctive wiring, while halogen setups use a standard bulb with a simpler harness. The owner's manual or a label on the headlight housing will indicate the correct bulb type for your exact vehicle and trim level.
Summary
For 2011 Toyota Sienna models with halogen headlights, use H11 for low beams and 9005 for high beams, with H11 also serving as the fog light bulb if equipped. If your Sienna has HID headlights, the low-beam bulbs are D2S or D4S depending on the ballast, and the high beam configuration varies by trim. Always confirm with the manual or headlight housing label, and consider replacing bulbs in pairs to maintain consistent brightness and color.
Are H11 and 9005 the same bulb?
Difference between these bulbs will be the O-ring on the base. H11 on the left side will have a big pronounced O-ring on the base of the bulb versus the 9005.
Do I need H11 or 9005?
H11 bulbs are designed for use as low beam headlights, while 9005 bulbs are typically used for high beams. This results in a higher brightness level for the 9005 bulbs compared to the H11 bulbs.
