Common bulb sizes for a 2007 Honda Ridgeline include H11 for the low-beam headlights, 9005 for the high beams, H3 for fog lights (if equipped), and 3157 for front and rear signal/taillights. Interior map and dome lights typically use 194 or 168 wedge bulbs. Always verify with your owner’s manual or by inspecting the actual bulb in your vehicle, since trim level and production date can affect exact sizes.
Exterior lighting: headlights, fog lights, and signals
The Ridgeline’s exterior lighting uses a handful of standard halogen bulb sizes. The following list covers the most common configurations found on 2007 models with factory lighting. If your truck is missing fog lights or uses a different assembly, sizes may differ.
- Headlights — Low beam: H11; High beam: 9005
- Fog lights — H3 (only if your exact trim is equipped with fog lights)
- Front turn signals — 3157 (some assemblies may use similar dual-filament bulbs; verify by removing the old bulb)
- Rear taillights/brake lights — 3157 (dual-filament type commonly used for taillight and brake functions)
- Backup/reverse lights — 921 (standard auxiliary reverse bulb on many Ridgeline setups)
Conclusion: Use the sizes listed above as a baseline, but confirm each bulb physically or via the manual, since trim and production date can cause variations.
How to verify exterior bulb sizes
For accuracy, inspect the existing bulb in the socket or remove it to read the base code, consult the owner’s manual, or check a trusted parts supplier’s fit guide for your exact VIN/trim. If you’re unsure, a quick visit to an auto parts store with the old bulb can yield an exact replacement without guessing.
Conclusion: Verification helps prevent ordering errors, especially for vehicles with optional lighting packages or regional variants.
Interior and auxiliary lighting
Interior lighting on the Ridgeline generally uses wedge-style bulbs. The most common sizes for map lights, dome lights, and courtesy lights are 194 or 168, with some smaller fixtures using 158 or 161 in rare cases. Trunk or cargo area lights and glove box lamps may also follow these wedge-base sizes. If your interior lights aren’t functioning or burn out, these are the typical replacements to try first.
- Map lights and dome lights — 194 or 168
- Glove box and courtesy lamps — 194 or 168
- Cargo/trunk area lights — typically 194/168 variants or a similar wedge bulb depending on exact fixture
Conclusion: Interior bulb sizes on the Ridgeline are mostly wedge types like 194/168; confirm by removing the lens assembly if you’re unsure.
Summary
The 2007 Honda Ridgeline commonly uses H11 for low-beam headlights, 9005 for high beams, H3 for fog lights (if equipped), and 3157 for front and rear signal/taillights, with 921 for backup lights. Interior map and dome lights usually take 194 or 168 wedges. Always verify by inspecting the existing bulb or consulting the owner’s manual or a parts specialist to account for trim and production differences.
