Description
xUpgrade headlights with streamlined wiring
The True Mods H6054 H4 wiring harness from ONLINE LED STORE is designed to simplify LED headlight upgrades on vehicles with negative switched circuits. This universal kit handles high and low beams via a plug-and-play relay system, helping you transition to brighter illumination without heavy rewiring.
Built for real-world use, it combines two sturdy relays, high-temperature ceramic sockets, and a heat-resistant polycarbonate loom. The result is a tidy, durable path from a negative-trigger ground to a positive-switched headlight setup, while preserving your stock wiring and enabling a reversible installation if needed.
What makes it practical
- Plug-and-play compatibility with common sockets such as 7x6/5x7 H6024, H6024 (2D1), 4x6/6x4 sealed beams, and H5006 (2C1).
- Two relays and fused protection to help manage high-beam and low-beam circuits safely.
- Heat-proofing features: ceramic sockets and a heat-resistant loom to resist engine bay heat.
Real-world fit and usage
- Designed for a broad range of vehicles, including models from Toyota, Subaru, Jeep, and more.
- Preserves original wiring so you can revert to stock if you decide to revert later on.
- Easy to install in minutes for many older and newer headlight configurations, minimizing downtime.
Quality and reassurance
The kit is brand-new, backed by a 1-year warranty from the manufacturer. While results can vary by vehicle and headlight condition, the harness is built to endure typical road conditions and climate exposures in daily use. With the right LED lamps, users may notice crisper cutoff lines and more even light distribution, though outcomes vary by setup.

Q: Does the harness require cutting the factory wiring?
