Interior Lighting
Interior Lighting: swap dim factory bulbs for LEDs you can actually see by
An interior lighting kit replaces the factory incandescent bulbs in your dome, map, footwell, cargo and door lights with LEDs. The job is simple in principle: pull the old bulb, seat the LED in the same socket or panel location, and check polarity so it lights up. The payoff is brighter, cleaner light for reading a map, finding dropped keys, or loading the cargo area at night. Some kits are plain white for a factory-plus look; others add color for cabin ambiance. It is one of the easier interior upgrades to do yourself with hand tools.
What ThreePiece stocks
This category carries 3 products from 2 brands - Diode Dynamics and ORACLE Lighting. Current in-stock pricing runs from $66 to $213, which is the range for what is on the shelf now rather than a fixed promise. Two of the kits are vehicle-specific and one is a universal color-changing set.
- The Diode Dynamics Stage 1 Cool White kit for the 2015-2019 Subaru WRX is the entry point at $65.67.
- The Diode Dynamics Stage 2 Cool White kit for the same WRX adds more coverage at $102.67.
- The ORACLE Fiber Optic LED ColorSHIFT 6-piece kit tops the range at $212.81 with color-changing output.
How to choose
The first split is direct-fit versus universal. The two Diode Dynamics kits are built specifically for the 2015-2019 Subaru WRX, so the bulbs match the factory locations and you are not guessing at sizes. Between them, Stage 1 covers the core lights, while Stage 2 extends coverage further for a fuller cabin change. Both are Cool White, so pick these if you want a crisp, consistent look.
The ORACLE ColorSHIFT kit is the different animal: a 6-piece fiber optic set that changes color, aimed at ambiance rather than a straight bulb-for-bulb swap. It sits at the top of the price range and is the choice if you want adjustable color in the footwells and cabin. If you drive a WRX and want plug-in simplicity, go Diode Dynamics; if you want color and a more involved install, go ORACLE.
What else you need with it
Lighting is one piece of an interior refresh. If you are wiring in accessories alongside the LEDs, look at Electrical Accessories. Rounding out the cabin, browse Shift Knobs, Grips and Audio Systems. If you are pulling seats to route light wiring, Racing Seats and Seat Brackets are in the same section. Everything sits under the main Interior section.
