The Honda Element brake light utilizes a 7443 bulb size for the specific lighting components located at the rear of the vehicle. Data for the specified lighting requirements covers the period from 2003 through 2011.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Honda Element uses the 7443 bulb for both its brake and outer brake positions across all listed model years, spanning 2003-2006 and 2009-2011.
The 7443 is a dual-filament wedge bulb of the T20 type, rated at 12V with a wattage split of 21W and 5W across its two filaments, conforming to ANSI standards recognized in the US and Canada.
The dual-filament design of the 7443 allows it to serve two lighting functions within a single housing, with the higher-wattage filament handling the brake signal and the lower-wattage filament typically serving a secondary function such as a tail light.
The center high mount stop light on the Honda Element uses the 7440 bulb across all listed model years, spanning 2003-2006 and 2009-2011.
The 7440 is a single-filament wedge bulb of the T20 type, rated at 12V and 21W, also conforming to ANSI standards recognized in the US and Canada.
Although the 7443 and 7440 share the same T20 wedge form factor and operate at 12V, they are not interchangeable. The 7443 carries two filaments while the 7440 carries one, and substituting one for the other in a given socket would result in incorrect or non-functional lighting behavior.
The consistent use of the 7443 across the brake and outer brake positions indicates that both positions share the same bulb specification throughout all listed model years of the Honda Element.
