The Baja Designs S1 Universal Hitch Light Kit (MPN 448153) mounts one S1 Wide Cornering LED pod in a bracket that fits any standard 2-inch receiver, so you get rear work and reverse light without wiring into the bumper or cab. The manufacturer rates each S1 at 2,320 lumens. Choose this kit over a generic hitch light when you want Baja's S1 optics, a published installation sheet, and a choice between automatic reverse activation and an independent switch.
The trailer adapter harness version is built for vehicles with a 7-pin trailer connector. Plug it in and the light illuminates when the vehicle is put into reverse. Vehicles without a 7-pin plug can use the toggle switch harness instead, which includes a 10-foot extension and runs the light on a switch you control for reversing, hitching, or trail work. Owners on user forums say the install is straightforward, but one 4Runner 6th-gen owner found the light body blocked the hitch-pin holes after drilling, so check clearance on your exact vehicle before you start. Searches for 2-inch receiver LED reverse light, 7-pin plug-and-play hitch light, and S1 hitch light install tend to lead to this kit.
The trailer adapter harness version does. The manufacturer says that if your vehicle has a 7-pin trailer plug, you can use the trailer adapter harness for a plug-and-play install. Vehicles without one should use the toggle switch harness setup.
Yes, when the trailer adapter harness is used. The manufacturer states the S1 illuminates automatically when the vehicle is put into reverse.
Owners on user forums recommend a locking hitch pin so the light cannot be pulled out of the receiver when the vehicle is left unattended. Confirm the pin fits your receiver before buying.
Per the manufacturer's installation sheet, park on level ground with the ignition off and gather a 2.5mm Allen key, a step-drill bit, and a marking pen. Slide the hitch mount fully into the receiver, mark where the hitch pin holes align on each side, remove the bracket, and step-drill those marks. Bolt the S1 onto the bracket, making sure the side bolts sit flush so the assembly still slides completely into the receiver. Insert the hitch pin through the receiver and bracket, then plug the harness into your vehicle's trailer connector. Check hole placement against your vehicle's clearance before drilling, since owners on user forums have reported the light body can block the pin holes on some trucks.
