Choose by the exact year and original lamp listed below. These applications do not establish fitment for a 2024, 2025 or 2026 Gladiator.
2020–2023 fog lamps: original removable bulbs only
These Diode Dynamics fog bulbs do not replace factory LEDs. Choose SL2 in Cool White (DD0477P) or Yellow (DD0478P), XP80 Cool White (DD0173P), or HP48 Cool White (DD0167P). HP48 is a cosmetic upgrade.
Installation for HP48 and XP80: shave the bulb alignment tab completely flush for proper fitment. Do this only for the exact manufacturer-listed application. This requirement is specific to HP48 and XP80.
Sold as a pair (two bulbs). Manufacturer fog application and installation notes.
2020–2021 halogen headlamps only
The H13 high/low-beam White SL2 pair (DD0485P) is listed for 2020–2021 Gladiator halogen headlamps. It does not replace factory HID or integrated LED assemblies. The bulbs are polarity-specific.
LED headlight conversions may not comply with FMVSS regulations. Check your local state or provincial laws.
Manufacturer headlight use notes
Diode Dynamics states that these bulbs are not DOT compliant for headlamp use on public roads in the United States and requires use only in compliant applications.

Factory LED service and bed-light notes
For 2021–2025, Jeep directs owners to an authorized dealer for LED bulb replacement; the 2026 manual recommends dealer service. The front side-marker and LED fog procedures replace the lamp assembly; the high-mounted stop lamp uses an LED assembly, and the license lamps require dealer LED service.
These manuals describe optional bed lights but give no cargo bulb code or technology. Identify that lamp separately. Use the specified bulb size and type, and avoid touching halogen bulb glass.

2020 lamp service and bed-light notes
Jeep advises dealer service for halogen headlamps and front park/turn and fog bulbs. Front side markers and LED fog lamps are replaced as assemblies. The tailgate-mounted high stop lamp and license lamps require dealer LED assembly service. The rear bulb-removal procedure does not change the chart’s LED side-marker or Premium rear-lamp specifications.
Optional bed lights illuminate the bed and cargo area, but the manual gives no replacement bulb code or technology for them. Identify these lamps separately; the interior Soundbar Dome Lamp entry does not specify an exterior bulb.

Common questions
Does every 2021–2026 Gladiator use H13 headlights?
No. Jeep lists H13 for the headlamp row and LED for Premium Head Lamps. Check which headlight assembly is installed before choosing a replacement.
Which fog bulb do the 2021–2026 manuals list?
Base Fog Lamps use PSX24W in Jeep’s chart. Premium Fog Lamps are LED. Match the exact lamp and application rather than treating another bulb name as interchangeable.
Can I use a 921 reverse bulb in my 2026 Gladiator?
Jeep lists 7440 for the Rear Base Tail Lamp Backup Bulb. A Diode Dynamics application lists 921, so identify the original lamp and bulb before choosing an upgrade. Factory LED assemblies require separate identification.
