The primary difference between H4 and H7 LED bulbs lies in their beam functionality: H4 is a dual-beam bulb containing two filaments (high and low beam) in a single unit, whereas H7 is a single-beam bulb used for either high or low beam. When upgrading to LED, you must match the specific base type (3-pin for H4, 2-pin for H7) to your vehicle’s existing housing.<\/strong><\/p>\n
