For most 2009 Ridgeline models, the headlights use standard halogen bulbs: low beams, high beams, and fog lights each have their own bulb type. The typical configuration is low beams with H11, high beams with 9005, and fog lights with H11, though trim differences and optional headlights can change this. Always verify on your specific vehicle to be sure.
Bulbs by function
The Ridgeline’s lighting system is organized by headlight function. Below is the common setup you’ll encounter on many 2009 models.
- Low beam headlights: H11
- High beam headlights: 9005 (HB3)
- Fog lights: commonly H11 on many trims
In short, the widespread arrangement is H11 for the low beams and fog lights, with 9005 for the high beams. Some trims or aftermarket headlights may use different bulbs for fog or for a different low-beam configuration, so check your manual or the bulb you currently have if you’re unsure.
How to confirm the exact bulb you need
To be certain you purchase the correct bulb for your specific Ridgeline, follow these steps.
- Consult the owner's manual’s bulb replacement section for the exact type and position (low beam, high beam, fog).
- Remove (or inspect) the current bulb to read the markings on the base or glass, which typically show the bulb type (e.g., H11, 9005).
- If you’re unsure after inspection, use a vehicle-specific bulb finder on an auto parts site or contact a Honda dealer with your VIN for accuracy.
- Confirm whether your vehicle has stock halogen headlights or an aftermarket HID retrofit, since HID setups use different bulbs (and ballasts) entirely.
When installing a new bulb, handle the glass with gloves or a clean cloth to avoid skin oils, which can shorten bulb life and performance.
HID options and aftermarket considerations
Stock versus aftermarket lighting
The 2009 Ridgeline was primarily equipped with halogen reflectors. An optional HID (high-intensity discharge) headlight package would use different bulbs (such as D1S/D2S) and ballast systems, not interchangeable with the standard H11/9005 bulbs. If your Ridgeline has HID headlights, don’t substitute them with halogen bulbs and vice versa. Always ensure compatibility with your vehicle’s electrical system and harness.
Summary
For most 2009 Honda Ridgeline models, the standard bulb types are H11 for low beams, 9005 for high beams, and H11 for fog lights. However, trim or aftermarket configurations can vary, and some vehicles may have HID headlights that use entirely different bulbs. Always verify with the owner’s manual or by inspecting the current bulbs on the vehicle before purchasing replacements.
