The Hyundai Venue brake light requires 1157 or P21/5W bulb sizes depending on the specific configuration of the vehicle. Data for the bulb sizes covers the range from 2020 to 2024.
The year-by-year compatibility chart below provides a quick reference to verify the correct bulb size for your vehicle.
The 1157 is a dual-filament bulb rated at 12V with filaments drawing 21W and 5W respectively, mounted on a BAY15d bayonet base. The dual-filament design allows a single bulb to serve both brake and tail light functions at different brightness levels.
The 921 is a single-filament wedge-style bulb in a T15 form factor, rated at 12V and 16W. The wedge base relies on tension from the socket contacts rather than a locking bayonet mechanism to hold the bulb in place.
Both the 1157 and 921 are ANSI-standardized bulb types recognized across the US and Canadian markets, meaning they follow consistent electrical and physical specifications regardless of manufacturer.
The Hyundai Venue uses the 1157 for the brake light position across the 2020-2021 and 2023-2024 model years, though the 2020-2021 entries carry a fitment condition specifying compatibility only with Halogen Capsule Headlamp configurations.
The halogen capsule headlamp condition on the 2020-2021 Venue brake light entries indicates that the 1157 fitment is tied to a specific trim or factory lighting package, and vehicles equipped with a different headlamp type may not share the same brake bulb specification.
The center high mount stop light on the Venue uses the 921 wedge bulb across the 2020-2023 model years without any trim-level or configuration conditions attached.
The 1157 and 921 are not interchangeable. The 1157 uses a BAY15d bayonet base with two filaments, while the 921 uses a wedge base with a single filament, making the socket types and electrical configurations incompatible with one another.
The 2024 Venue brake light specification lists the 1157 without any configuration condition, unlike the 2020-2021 entries, indicating an unconditional fitment for that model year.
