Jeep Wrangler JL and Gladiator JT Headlight Upgrade Guide

The Jeep Wrangler JL and Gladiator JT use 7 in. round headlights. Replacement assemblies are a common upgrade for brighter, whiter light. Shop our Wrangler JL headlights.

Check what your Jeep has now

  • Factory halogen: look for headlights listed for halogen-equipped models. Some need anti-flicker harnesses or decoders.
  • Factory LED: some trims came with LED headlights from the factory and use different connectors and mounting. Buy assemblies listed for factory LED models.
  • Model year: confirm the year range on the product page.

What to look for

  • DOT/SAE compliance for street use, where listed.
  • A plug-and-play connection for your model.
  • Whether a mounting ring or bracket is needed.
  • Aiming the headlights after installation so you don't blind oncoming drivers.

Halogen vs. LED

Factory halogen headlights put out a yellower light. LED assemblies generally produce whiter light and draw less power. For best results, choose a full LED headlight assembly designed for the 7 in. round housing rather than just a bulb, because the reflector or projector must be designed for the light source to control glare.

Beam pattern and glare

A good headlight has a sharp cutoff on low beam, so light goes down the road and not into oncoming drivers' eyes. Look for products marked DOT or SAE compliant if you drive on the street, and check local laws.

Features to compare

  • Halo or DRL rings: some assemblies add daytime running lights or turn signal functions. Check how they wire in.
  • Heated lenses: LED headlights run cooler than halogen, so snow and ice can build up on the lens. Some models include a heated lens.
  • Housing: look for sealed, weather-resistant housings for off-road and wet use.
  • Warranty: compare the manufacturer's warranty terms.

Installation

Most JL and JT headlights mount from the front after removing the grille, and use the factory connector or a supplied adapter. Disconnect the battery if the instructions say so, test the lights before reinstalling the grille, and aim them on a flat surface against a wall after installing. Add matching fog lights and auxiliary lighting to complete the upgrade.

If your Jeep already has factory LED headlights, an aftermarket set is mostly about beam pattern, extra features or style, so compare those details before you buy.
