Kia Rondo high beam headlight bulbs use H1 size while low beam headlight bulbs use H11B size. Replacement chart data covers 2007 to 2010 vehicle production years with corresponding bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H1 bulb is a single-filament halogen type operating at 55 watts with a P14.5s base. It is used exclusively for the high beam headlight position across all Kia Rondo model years covered in these specifications, spanning 2007-2010.
The H11B bulb fills the low beam headlight position on the Kia Rondo for all four model years listed, from 2007-2010, indicating a consistent lamp fitment across the full production run represented here.
The H11B is a single-filament halogen bulb rated at 55 watts. It shares the same PGJ19-2 base type as the standard H11, but the two are not interchangeable due to a physical tab difference on the H11B base that prevents an H11 from seating correctly in an H11B socket.
The H1 bulb produces a focused, narrow beam pattern, which suits its role in the high beam circuit where concentrated long-range light projection is required.
Because the Rondo uses separate bulbs for high and low beams rather than a dual-filament unit, each circuit operates independently. A failure in one beam position does not affect the other.
The H11B designation is a market-specific variant found predominantly in vehicles sold in North America. Substituting a standard H11 bulb in an H11B socket risks an improper fit and potential electrical contact issues.
