2024 Jeep Gladiator Bulb Sizes: The Ultimate Reference Guide

Quick Reference

The 2024 Jeep Gladiator continues to offer a blend of rugged capability and modern convenience, with its lighting system reflecting this duality. Depending on your trim level and chosen options, your Gladiator may come equipped with traditional halogen bulbs or advanced LED lighting from the factory. Understanding these differences is key when considering replacements or upgrades.

Most base model Gladiators will feature halogen headlights and fog lights, utilizing the common H13 bulb for both low and high beams, as well as DRL functionality. Fog lights typically use a 2504 halogen bulb. However, higher trim levels or specific option packages will include a full LED lighting group, which replaces these halogen bulbs with integrated LED units for superior brightness and longevity. In these cases, individual bulb replacement for the headlights, DRLs, and fog lights is generally not possible as they are sealed LED assemblies.

For the remaining exterior lighting – front and rear turn signals, brake lights, tail lights, reverse lights, and license plate lights – the 2024 Gladiator primarily uses incandescent bulbs across all trims. Front turn signals typically use a 7443A, while rear turn signals, brake lights, and tail lights often share a 7440 bulb. Reverse lights are also commonly a 7440. License plate and side marker lights usually utilize the smaller W5W or 194 bulb. Similarly, interior dome and map lights are typically incandescent (578 for the dome, 194 for maps) unless the vehicle is equipped with an optional interior LED lighting package.

Upgrading from halogen to LED bulbs in your 2024 Jeep Gladiator can significantly improve visibility and give your truck a more modern aesthetic. However, there are several factors to consider:

• CANBUS Errors: Modern vehicles like the Gladiator use a CANBUS (Controller Area Network Bus) system to monitor electrical components. Halogen bulbs draw more power than LEDs. When you switch to LEDs, the lower power draw can be misinterpreted by the CANBUS system as a
