WEIMELTOY LED Interior Light Kit for Toyota 4Runner 2006–2021 — 18-Piece CANBUS Plug-and-Play Set

This comprehensive set replaces common incandescent bulbs across the 4Runner — including dome, map, door, trunk, glove box, vanity mirror, puddle, and backup lights — with high-output LED components that are rated for CANBUS systems to prevent dashboard errors. The kit includes a mix of 194, 31mm festoon, and 921 bulbs plus an installation tool and a placement guide so you can update every listed lighting point without modifications. The files below explain fitment, brightness, installation tips, and who benefits most from this upgrade.

Will these LEDs fit my Toyota 4Runner year and trim?

Yes — the kit is designed for model years 2006 through 2021 and is intended to cover all factory configurations for those years. It targets the common bulb sockets used across trims, so it works for base and higher-end versions alike.

• Compatible with 2006–2021 4Runner models across trims.
• Includes bulbs for dome, map, door, trunk, glove box, vanity, puddle, and reverse lights.
• Placement guide reduces guesswork about which bulb goes where.

How difficult is installation and what tools do I need?

Installation is intended to be straightforward: the kit is plug-and-play and comes with an extraction tool and a placement guide. No splicing, relays, or additional parts are required for most vehicles, and the package aims to avoid triggering CANBUS error codes.

• Includes an installation tool for safe bulb removal and insertion.
• Plug-and-play bulbs fit factory sockets; no wiring changes expected.
• CANBUS-compatible design minimizes error lights in 99% of cars.

How much brighter are these LEDs compared with stock bulbs?

The LEDs use high-quality chips and constant-current circuitry to deliver a noticeable brightness increase — advertised at roughly three times the output of stock incandescent bulbs. The result is clearer interior illumination and more visible license plate and backup lighting.

• High-output LED chips for improved cabin visibility.
• Constant-current IC provides stable light and longer life.
• Brighter reverse and license plate lights enhance visibility to others.

What is included and what support does WEIMELTOY provide?
