Additional Notes

The 9003 is a dual-filament halogen bulb operating at 12 volts, with a high-beam filament rated at 60 watts and a low-beam filament rated at 55 watts. It uses a P43t base, which is a standardized bayonet-style fitting common across many halogen headlight applications.
The 9003 bulb type carries an ANSI designation recognized in the United States and Canada. The same bulb is sold under the designation H4 in international markets, though the two share identical physical and electrical characteristics.
The John Deere ProGator 2020A uses the 9003 bulb for the low beam headlight position across the 2010-2012 model years, with all listed fitments designated as European Model variants.
Because the listed fitments are specifically designated as European Model variants, the 9003 specification may not apply universally to all regional configurations of the ProGator 2020A, and fitment should be confirmed against the specific regional build of the unit in question.
