The typical setup for a 2014 Toyota Sienna with halogen headlights is H11 for the low beams and 9005 for the high beams; fog lights usually use H11 or H16 depending on trim. If the vehicle has HID headlights, you’ll use HID bulbs with a ballast (often D4S) rather than standard halogen bulbs.
Halogen headlight bulb sizes you’ll likely need
These sizes cover the most common halogen configurations on the 2014 Sienna. Always verify on your vehicle, since trim and regional markets can change the exact specification.
- Low beam: H11
- High beam: 9005 (HB3)
- Front fog lights: typically H11, though some trims use H16
In most cases, these are the bulbs you’ll need for standard halogen headlights. If your Sienna uses HID or LED headlights, refer to the next section for alternatives.
HID or LED headlight options on the 2014 Sienna
Some 2014 Sienna models came with HID headlights as an option. If your Sienna has HID, the low/high beams use HID bulbs with a ballast rather than standard halogen bulbs. LED headlights, when present, use modules rather than replaceable bulbs in this era.
- HID: D4S or D2S‑type bulbs with ballast (verify which your car uses). Replacement may require the ballast and proper alignment; some setups are serviced as a unit.
- LED: LED headlamps use modules; when a module fails, replacement typically involves the entire LED unit rather than swapping a single bulb.
Always confirm the exact type for your trim and market by checking the owner’s manual, the bulb label, or with a parts professional. Mixing halogen and HID components can damage electrical systems.
Summary
For most 2014 Sienna models with halogen headlights, use H11 for low beams and 9005 for high beams, with fog lights typically being H11 or H16 depending on trim. If your vehicle is equipped with HID headlights, use the corresponding HID bulb type (D4S or D2S) with its ballast, and LED headlights use replaceable modules rather than bulbs. Always verify the exact bulb type on your specific vehicle and replace bulbs in pairs when possible to maintain consistent brightness and color.
