LOYO's 9-inch round LED headlights are engineered as direct-fit replacements for the Jeep Gladiator JT, covering all model years from 2020 through 2026. Each set delivers up to 16,000 lumens on high beam and 9,000 lumens on low beam — powered by genuine Philips LED chips — compared to roughly 1,200–1,500 lumens from the factory halogen units. That is a measurable, real-world brightness improvement that transforms nighttime visibility both on highway and off-road trail.
Every headlight in this collection is DOT approved and fully legal for public road use across all 50 US states. IP67 waterproof sealing and die-cast aluminum housings ensure reliable performance in rain, mud, and water crossings. Installation requires no wiring modifications: each unit uses the factory H4 plug-and-play connector and fits the stock 9-inch housing — most owners complete the swap in under 30 minutes with basic hand tools.
Why Upgrade the Jeep Gladiator JT Factory Headlights?
The Gladiator JT left the factory with halogen headlights rated at approximately 55W per bulb, producing around 1,200–1,500 lumens each. LOYO's LED replacements operate at 30W on low beam and 60W on high beam per unit (120W total per pair), yet produce significantly more usable light through Philips chip technology and a 9D patented optical lens system. The result is a focused, far-reaching beam pattern with a sharp "Z" cutoff line that maximizes road illumination without blinding oncoming drivers.
Beyond brightness, LED technology offers practical advantages for Gladiator JT owners: a rated lifespan of 50,000–80,000 hours versus 500–1,000 hours for halogens, lower current draw that reduces strain on the JT's electrical system, and instant full-brightness output in cold weather where halogens can take time to reach peak output.

Frequently Asked Questions
What size headlights does the Jeep Gladiator JT use?
The Jeep Gladiator JT (2020–2026) uses 9-inch round headlights. LOYO's LED replacements are built to OEM 9-inch dimensions for a direct drop-in fit with no modifications to the housing or wiring.
Are LOYO LED headlights DOT approved for street use on the Gladiator JT?
Yes. All LOYO headlights in this collection carry DOT approval and meet FMVSS 108 standards for both high and low beam output, making them street-legal across all 50 US states.
Do I need to modify my Jeep Gladiator JT wiring to install LOYO LED headlights?
No. LOYO headlights use the same H4 connector as the factory harness. Installation is plug-and-play — no splicing, no relay harness, no additional components required. Most owners finish the install in 20–30 minutes.
Are the Jeep Gladiator JT and Wrangler JL headlights the same size and interchangeable?
Yes. The Gladiator JT and Wrangler JL use identical 9-inch round headlight housings with the same H4 connector, so any headlight compatible with one model is compatible with the other.
How bright are LOYO LED headlights compared to the factory Gladiator JT halogens
Factory JT halogens produce approximately 1,200–1,500 lumens per bulb. LOYO's Sunlight series delivers 9,000 LM on low beam and 16,000 LM on high beam per set — a substantial improvement that is immediately noticeable at night and on unlit trails.
Are LOYO Gladiator JT LED headlights waterproof for off-road use?
Yes. All units carry IP67 waterproof certification, meaning they are fully sealed against dust and can withstand water immersion up to 1 meter. This makes them suitable for river crossings, heavy rain, and muddy trail conditions common to Gladiator JT use cases.
Do LOYO LED headlights cause flickering or error codes on the Jeep Gladiator JT?
Most Gladiator JT owners report no flickering or CANBUS error codes with LOYO LED headlights due to the matched load design. If your specific build does show a warning, a simple resistor adapter (available separately) resolves the issue.
What warranty does LOYO offer on Gladiator JT LED headlights?
LOYO provides a 12-month manufacturer's warranty on all LED headlights in this collection. Contact support@loyoled.com for warranty claims and support.
