Found this:
“ comparison between h3 and h4 light bulbs H3 and H4 light bulbs serve different purposes in automotive lighting. The H3 is a single filament bulb primarily used for fog lights and auxiliary lighting, while the H4 is a dual-filament bulb designed for main headlights, providing both high and low beam functionality.
