The exact bulb type depends on your model year and trim. In many Tucsons, the rear brake/taillight uses a dual-filament halogen bulb from the 3157/3157A family or the 7443 family, but newer models with LED tail lights may not use a replaceable bulb. Always verify with the owner's manual or by inspecting the bulb in the housing.
How to identify the correct brake light bulb for your Tucson
To determine the exact bulb for your vehicle, follow these steps:
- Check the owner's manual for the Bulbs section, which lists the replacement bulb number for your year and trim.
- Inspect the rear light assembly: remove the lens or cover and read the bulb number printed on the base or the socket; common numbers include 3157, 3157A, and 7443.
- Use Hyundai's official parts catalog or a reputable auto parts retailer; enter your year, make, model, and trim to retrieve the exact bulb specification.
- Note whether your Tucson uses an LED tail lamp (in which case there may be no user‑replaceable bulb, or you may need the entire unit).
Concluding the identification process ensures you purchase the correct replacement and avoid compatibility issues, such as improper mounting or voltage mismatches. Always handle bulbs with gloves to prevent oil contamination on the glass.
Typical bulb families you may encounter
While the exact bulb can vary by generation and trim, several bulb families are frequently used in Hyundai Tucsons. This section provides a general guide to what you might encounter, with emphasis on verification rather than assumption.
- 3157 and 3157A: Common dual-filament bulbs used for tail and brake functions in many older Hyundai Tucsons.
- 7443 and 7440: Other widely used dual‑filament or single‑filament/specialized bulbs found on some rear lighting assemblies.
- 2057 and related variations: Less common in later years but possible in certain markets or trim levels.
- LED rear tail lights: In newer models, the rear lighting may be LED, meaning bulbs are not user-replaceable; replacement may require an OEM module or assembly swap.
Concluding this section, the most reliable path to the exact bulb is to reference the manual or an official parts lookup for your specific year and trim. Mismatched base types or wattages can cause poor illumination or electrical issues.
Summary
For a Hyundai Tucson, there isn’t a one-size-fits-all bulb. The safe, accurate approach is to confirm the exact bulb type via your owner's manual, the rear light assembly, or Hyundai’s official parts catalog using your year and trim. Common possibilities include 3157/3157A and 7443 family bulbs for halogen setups, while LED-equipped models may not require or permit a bulb replacement. When replacing, handle bulbs with care, do not mix different technologies in the same housing, and replace in pairs where recommended by the manufacturer.
