The brake light on a 1998 Ford Explorer typically uses a dual-filament 3157-type bulb. This bulb is commonly used in the rear tail/brake assemblies of Explorers from that era. However, variations by market or trim mean you should verify the exact bulb on your specific vehicle.
Understanding the rear lighting setup on the 1998 Explorer
The 1998 Explorer uses a combined rear taillight assembly on each side that houses the brake lamp, taillight, and turn signal. Because these lamps rely on two filaments within a single bulb, a dual-filament bulb is the standard choice. The exact bulb number can vary by market and production date, so checking the bulb itself or the owner's manual is the best way to confirm.
Identifying the correct bulb
To determine the exact bulb for your vehicle, inspect the bulb inside the taillight housing or consult the service manual. The most common option for U.S.-market Explorers from this era is the 3157 dual-filament bulb. Some export models or earlier builds may use other dual-filament types such as 1157, so verification is important.
Common bulb types you might encounter in the 1998 Explorer rear lamps:
- 3157 dual-filament bulb (the standard for brake/taillight in most US and many global versions)
- 1157 dual-filament bulb (less common in US-spec, but found in certain markets or retrofit scenarios)
When replacing, ensure you match the exact bulb number and wattage as specified by the manual or the bulb markings on the existing bulb. If in doubt, consult a dealer or service manual for your specific VIN and production date.
Practical tips for replacement
Safety first: Park on a flat surface, turn off the ignition, and allow the tail lights to cool before handling. Access the taillight cluster according to your model (often via the trunk or liftgate interior panel). Remove the bulb from its socket by twisting or pulling gently, then replace with the correct dual-filament bulb. For optimal reliability, replace both rear bulbs if one has failed or shows signs of wear.
Summary
For most 1998 Ford Explorers, the brake light uses a dual-filament 3157-type bulb, typically labeled as 3157 or 3157A. Always verify by inspecting the bulb marking or checking the owner's manual, as some markets or trims may use a different dual-filament bulb such as 1157.
