This 2019 Honda Ridgeline bulb size guide helps you verify the correct bulb by lighting position, so you can replace the right part the first time. Whether you are working on the headlights, tail lights, interior lamps, or cargo-area lighting, this page organizes the available bulb sizes for the 2019 Ridgeline in a simple, position-by-position format.
The 2019 Honda Ridgeline may use different bulb types depending on the headlight setup and lighting package. Some positions use LED assemblies, while others use replaceable halogen bulbs such as H11, 9005, 7444NA, 7440, 194, 168, or 2721/74. Use the bulb chart on this page to match the exact light location before ordering replacements.
Fitment can vary by trim, package, market, and body style, so it is smart to confirm whether your Ridgeline has halogen headlights or factory LED headlights before buying parts. That matters for items like the low beam, daytime running light, and cargo-area light, since the bulb type can change with the lighting package. If you are considering an aftermarket LED conversion, make sure the bulb base, physical size, and beam pattern are compatible with the housing. The safest approach is to compare the installed bulb to the chart and, when possible, check the old bulb before purchase.
