Kia Soul EV high beam and low beam headlight bulbs both use H7 size replacement bulbs. The chart covers 2015 to 2019 production years with bulb size specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The H7 bulb is a single-filament halogen lamp operating at 55 watts on a 12-volt circuit, producing light through a tungsten filament enclosed in a halogen gas-filled quartz envelope.
The Kia Soul EV uses the H7 bulb type for both high beam and low beam headlight positions across the 2015-2019 model years.
The H7 bulb uses a two-pin PX26d base, which is a keyed connector designed to allow fitment in only one orientation, preventing incorrect installation.
Because the same H7 specification applies to both the high beam and low beam positions, the two headlight assemblies on this vehicle accept physically identical bulbs despite serving distinct optical functions.
H7 bulbs are not interchangeable with the similarly named H4 or H1 types, as each designation corresponds to a distinct base configuration and wattage rating that is incompatible with sockets designed for other types.
The H7 standard is defined under ECE Regulation 37, meaning bulbs carrying that certification conform to internationally recognized output and dimensional tolerances.
Aftermarket H7 variants, including xenon-enhanced halogen and LED retrofit versions, share the PX26d base but may differ in light output, color temperature, and regulatory compliance depending on the market in which they are sold.
