The Honda Element side marker utilizes a specific 168 bulb size for the lighting component located on the exterior of the vehicle. Data for the bulb size covers the range from 2009 to 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 two distinct bulb types across its side marker positions: the 168 and the 7443, both of which are ANSI-standardized for the US and Canadian markets.
The 168 bulb is a single-filament miniature wedge type in a T10 form factor, rated at 12V and 4.9W, placing it in the low-wattage range typical of parking and marker lighting applications.
The 7443 bulb is a dual-filament wedge type in a T20 form factor, rated at 12V with a 21W high filament and a 5W low filament, a configuration commonly associated with combined stop and tail or marker functions.
The front side marker position on the Honda Element uses the 168 bulb across all listed model years, spanning 2003-2006 and 2009-2011.
The rear side marker position splits across two different bulb types depending on model year: the 7443 is specified for 2003-2006, while the 168 is specified for 2009-2011.
The T10 and T20 designations refer to the wedge base width of each bulb, with T20 being physically larger than T10, meaning the two types are not interchangeable despite both using wedge-style bases.
The wattage difference between the 168 (4.9W) and the 7443 (21W/5W) is substantial, and substituting one for the other in the rear side marker socket would be electrically and physically incompatible.
The rear side marker on the Honda Element transitioned from the higher-wattage dual-filament 7443 in earlier years to the lower-wattage single-filament 168 in later years, reflecting a change in socket and circuit design between those production periods.
