1988-1998 Chevy / GMC 1500-3500 Roof 50" Light Bar Kit
Everything you need to run one 50" LED light bar on your 1988-1998 Chevy / GMC 1500-3500 — in one part number. No guessing which bracket fits, no separate harness order, no missing hardware the night before a trip.
What's in the kit
- Brackets: 1988-1998 Chevy/GMC 1500-3500 Roof Mounts — CAD-designed for the 1988-1998 Chevy / GMC 1500-3500 (OBS). They sit tight to the roofline above the windshield.
- Lights: One 50" LED light bar — pick your light bar series below.
- Wiring: 1 x Single Harness with inline fuse, relay and lighted switch — or swap it for the wireless switch panel below.
- Hardware: all mounting bolts and hardware included.

Every price above is the same as buying the pieces individually — the kit exists so the fitment is guaranteed and nothing shows up missing.
Wiring: harness or wireless switch panel
Every kit ships wired. The second dropdown lets you decide how:
- Plug-and-Play Harness (included) — 1 x Single Harness with relay, inline fuse and lighted rocker switch. This is the standard kit.
- Wireless Switch Panel (replaces harness) — swap the harness for the Wireless Switch Control Panel System, a multi-circuit panel you control from a wireless remote. Adds $360.00 to the kit.
Fitment
Fits 1988-1998 C/K 1500, C/K 2500, C/K 3500, Sierra (OBS). Direct bolt-on using factory mounting points — no cutting, no drilling, no permanent modification. If you are unsure about your exact trim or bumper, message us with your year, make and model before you order.
Install
Most builds go on in under an hour with hand tools. The harness runs from the battery to the lights with a relay, an inline fuse and a lighted rocker switch, so nothing is spliced into a factory circuit.
