The Baja Designs 447664 is an eight-light XL Linkable LED roof bar built for the Jeep Wrangler JL and Gladiator JT. Each lamp uses the XL Sport shallow moto housing and produces 3,162 raw lumens, according to the manufacturer. Aluminum links, extruded from 6061 alloy, let you tilt the array up to 45 degrees vertically and set the lamps straight or in an arc to follow your roofline.
Eight lamps spread a wide, continuous beam across rocky trails and brush, which a shorter bar cannot match. The pre-load support bracket is there to keep the assembly rigid on rough terrain, and stainless steel hardware and black rock guards come in the box. If your Jeep has factory upfitter switch provisions, the upfitter-harness version (447664UP) plugs into that switch. Otherwise, the toggle harness (640115) is the choice for a standalone on/off switch.
The manufacturer lists fitment for 2020–2026 Gladiator and 2018–2026 Wrangler JL, but excludes Mojave, Rubicon 392, and 4xE models. Expect some added wind noise, which the manufacturer warns is typical for any roof-mounted light. Search terms this kit matches include JL roof light bar, JT Gladiator LED roof bar kit, 8XL linkable roof light, and XL Sport linkable roof mount.
The manufacturer lists fitment for the Jeep Wrangler JL from 2018 through 2026 and the Gladiator JT from 2020 through 2026. The manufacturer states the bar does not fit Mojave, Rubicon 392, or 4xE models.
The manufacturer offers the kit with either an on/off toggle harness (640115) or an upfitter harness. The upfitter harness is intended for models with factory upfitter switch provisions.
The manufacturer warns that installing any roof-mounted lights causes a degree of added wind noise, depending on vehicle type and installed accessories.
The manufacturer publishes an installation sheet for this kit, so review it before you start and follow its order of steps. Confirm whether your Jeep has upfitter switch provisions before choosing between the toggle and upfitter harnesses, since that decides which wiring path you use. The kit includes two roof mounting brackets and a pre-load kit; set the pre-load bracket so the assembly stays stiff, then aim the lamps. Plan for added wind noise once the bar is installed.
