2022 Jeep Wrangler JL Bulb Sizes Reference Guide

Quick Reference: 2022 Jeep Wrangler JL Bulb Sizes

The 2022 Jeep Wrangler JL offers a range of lighting configurations depending on the trim level. Lower trims like the Sport and Sport S typically come equipped with traditional halogen bulbs, while higher trims such as the Sahara, Rubicon, and High Altitude often feature factory-installed LED lighting systems for the headlights and fog lights. It's crucial to identify your specific trim and whether your Wrangler has the optional LED Lighting Group to determine the correct bulb type.

For Low Beam and High Beam Headlights, Sport and Sport S models use a single H13 bulb that serves for both functions. If your Wrangler has the premium LED headlights, these are an integrated LED assembly where individual bulbs are not replaceable for the low beam. The LED high beam is also integrated into this assembly. Some Sahara and Rubicon trims might have a 9005 halogen bulb for the low beam if not optioned with the full LED package. Always double-check your vehicle's existing setup.

Fog Lights on Sport and Sport S trims generally use an H16 halogen bulb. However, if your Wrangler has the LED Lighting Group, the fog lights will be integrated LED units.

Daytime Running Lights (DRL) are typically integrated into the LED headlight assemblies for Wranglers equipped with the LED lighting package. For halogen-equipped models, the DRL function is often handled by the front turn signal bulb operating at a reduced voltage.

Front Turn Signals on Sport, Sport S, and some Sahara models use a 3157NAK incandescent bulb. Rubicon and High Altitude models with LED headlights usually have integrated LED front turn signals.

Rear Turn Signals across most trims utilize a 7440A incandescent bulb.

Brake Lights and Tail Lights commonly share the same 7443 incandescent bulb. This is a dual-filament bulb that provides both the dim tail light function and the brighter brake light function.

Reverse Lights across all trims typically use a 921 incandescent bulb.

License Plate Lights generally take a 194 incandescent bulb.

Side Marker Lights located on the front fenders usually use a W5W incandescent bulb.

For interior lighting, the Front Dome Light and Map Lights often use 194 incandescent bulbs. The Rear Dome Light (if equipped) commonly uses a 578 incandescent festoon bulb.

LED vs Halogen Upgrade Considerations

Upgrading from halogen to LED bulbs in your 2022 Jeep Wrangler JL can significantly improve light output and modernize its look. However, there are several key points to consider:

• CANBUS Errors: Modern Jeeps use a CANBUS (Controller Area Network Bus) system to monitor electrical components. LED bulbs draw less power than halogens, which can trigger
