Honda Insight Headlight Bulb Size

Honda Insight headlight bulbs utilize 9005 and 9003 sizes for high beam applications, with low beam configurations requiring H11 and 9003 bulb sizes. The replacement chart covers 2000 through 2014 model years with corresponding bulb size specifications.

The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.

Additional Notes

The 9003 bulb is a dual-filament halogen type rated at 12V with a 60W high beam filament and a 55W low beam filament, using a P43t base. Its dual-filament design means a single bulb serves both high and low beam functions within one housing.
For the Honda Insight across model years 2000-2006, the 9003 bulb handles both high and low beam duties, as both sub-parts share the same bulb size for those years.
The 9005 is a single-filament halogen bulb rated at 12V and 65W, using a P20d base. Because it carries only one filament, it is dedicated exclusively to high beam operation.
The H11 is a single-filament halogen bulb rated at 12V and 55W, using a PGJ19-2 base. It operates under the ECE standard but holds approval for use in the United States as well.
For the 2010-2014 Honda Insight, the high and low beam functions are split between two separate bulb types: the 9005 for high beam and the H11 for low beam. This means the two positions are not interchangeable, as the bulbs differ in base type, wattage, and filament count.
The 9005 and 9003 bulbs both follow the ANSI standard applicable in the US and Canada, whereas the H11 follows the ECE standard used in Europe and worldwide.
The P20d base of the 9005 and the P43t base of the 9003 are physically distinct, making those two bulb types incompatible with each other's sockets despite both being ANSI-rated halogen bulbs.
The PGJ19-2 base of the H11 differs from both the P20d and P43t bases, meaning the H11 is not physically interchangeable with either the 9005 or the 9003.
