Suzuki Reno headlight bulbs utilize H1 size for high beam and H7 size for low beam applications. The replacement chart covers 2005 through 2008 vehicle production years with corresponding bulb specifications.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The Suzuki Reno uses the H1 bulb for high beam headlights across its entire 2005-2008 production run.
The H7 bulb fills the low beam headlight position across the same 2005-2008 span, meaning the Reno uses two distinct bulb types that are not interchangeable between positions despite sharing identical voltage and wattage ratings.
Both the H1 and H7 are single-filament halogen bulbs rated at 12V and 55W, meaning each bulb handles only one lighting function rather than combining high and low beam output within a single unit.
The H1 uses a P14.5s base, while the H7 uses a PX26d base. These are physically different base configurations, which prevents cross-fitting between the two positions.
Both bulb types are governed by ECE standards, a regulatory framework used across Europe and much of the world, and both also carry approval for use in the United States and Japan.
