2020 Honda Insight bulb fitment uses LED lighting for both the low-beam and high-beam headlights. The supplied fitment data does not identify a replaceable halogen bulb size or list a projector/non-projector headlight distinction, so confirm the original lamp assembly before ordering a replacement.
- Fog lights, daytime running lights, parking lights, front and rear side markers, brake lights, center stop light, tail lights, and license plate lights are listed as LED.
- Front turn signals may use a 7440 bulb or an LED setup, depending on the vehicle’s configuration.
- The rear turn signal is listed as 7440A.
- Reverse lights use 921 bulbs.
- Interior fitment includes 194 or 7441 options for the dome and map lights.
- The trunk light may use a 168 or 917 bulb.
Because several exterior functions are LED-equipped and the front turn signal has more than one listed option, inspect the existing bulb or housing when servicing those locations.
