Lighting Accessories: the wiring, switches and mounts that make your lights actually work

A light bar or a set of pods is only half the job. The lighting accessories here are the parts that get power to those lights, switch them safely, and hold them where you want them. Think switched power harnesses with a relay so you're not running high current through a dash switch, upfitter switch panels that give you clean control of several circuits, roof mounts sized to a specific vehicle, and LED DRL grille inserts that add a factory-style daytime light signature. If you've ever wired an accessory light straight to a battery and blown a fuse, this is the category that fixes that habit.

These parts sit under the wider Lighting section, and they're what you reach for after you've picked the lights themselves.

What ThreePiece stocks

There are 59 products in this category right now, spanning three brands: Morimoto (the bulk of the range), Morimoto Offroad, and Pro Comp. Current prices run from $56 to $509 for what's in stock, so it covers everything from a simple wire harness to a full DRL grille insert set. That range is a snapshot of live inventory, not a fixed promise.

Concrete examples: the Pro Comp SS6 Universal Upfitter Switch Panel and the Pro Comp Dual Output Relay Wire Harness handle switching and power on the budget end. The Morimoto Offroad Switch Power Harness with 6 outputs steps that up, and the BangerBar Roof Mounts for the 2021+ Ford Bronco cover mounting. At the top of the price spread, the Morimoto XBG LED DRL Grille Inserts for the 2020-22 Ford Super Duty Platinum come in white and amber.

How to choose

Start with what you're wiring. If you're running one or two accessory lights, a relay harness like the Pro Comp dual-output unit is enough. If you're building out a truck with several circuits, an upfitter switch panel or a 6-output power harness saves you a rat's nest of wiring later. Mounts are vehicle-specific, so a Bronco roof mount won't help a Tundra. DRL grille inserts are a different animal again: they're cosmetic-plus-function items tied to one grille, so fitment is exact, not universal.

Of the 59 products, 23 list fitment data, covering years 2003 to 2024. Vehicles named in that data include the Toyota Tundra and Tacoma, Ford F150, Super Duty and Raptor, Ram, Lexus GX470, Chevrolet Silverado, GMC Sierra, Ferrari F430, and Jeep Wrangler JK, JL and JT. Universal items like the switch panel work across builds regardless.

What else you'll want

Accessories pair with the lights they power. Look at Pod Lights and Rock Lights for off-road builds, or Fog Lights and Headlights for the front end. For smaller upgrades, Bulbs and Side Markers round things out.
