Diode Dynamics Solid-State Relay Harness

 

Diode Dynamics Solid-State Relay Harness allows compatible lighting devices to draw power directly from the battery while using factory signals for activation. It is built for customers working with modern vehicles where factory circuits may flicker, shut off, or trigger warnings when aftermarket lighting draws power directly.

Solid-state switching provides a cleaner alternative to a traditional mechanical relay for many lighting projects. The harness is designed to help reduce flicker and warning issues while preserving factory signal control for multicolor, switchback, or single-color lighting systems.

This group includes multicolor and switchback-oriented relay harness options. One version is designed around multicolor controllers with Deutsch plugs, while the switchback version is designed for switchback and single-color drivers with multiple factory signal inputs.

The harnesses support up to 8 amps at 12 volts, or 96 watts DC, and use waterproof and shockproof construction for demanding vehicle environments. Operating voltage is 5-16V, giving the harness flexibility across compatible automotive signal applications.

Installation requires direct battery power, factory signal pickups, and careful routing of the harness. Customers should confirm the lighting system type, signal count, connector style, and total draw before final installation and testing.

Whether customers are upgrading for multicolor lighting control, switchback lighting, or cleaner factory-signal activation, the Diode Dynamics Solid-State Relay Harness delivers a focused lighting solution with clean integration and confident everyday usability. Now Available at LEER! The upgrade is especially useful for customers who want a finished result that looks intentional rather than improvised. Its compact, application-matched design helps the finished installation blend naturally with the vehicle. The result is a practical electrical or lighting upgrade that supports a cleaner final build.
