Universal Integrated Turn Signal Kit

The Universal Integrated Turn Signal Kit (Model 30120) from Painless Wiring addresses a critical need for custom vehicle builders and restoration enthusiasts: seamless signal integration without complex rewiring or bulky external modules. Whether you're fabricating a custom frame, modernizing a vintage chassis, or integrating aftermarket lighting into a heavily modified platform, this kit eliminates the guesswork of signal circuit design. It's engineered for builders who demand clean installations, OEM-style functionality, and the reliability to pass safety inspections on street-legal builds.

This integrated solution consolidates turn signal logic and distribution into a compact, single-unit assembly measuring 7.6 × 2.05 × 12.4 inches and weighing just 1.36 pounds—small enough to tuck behind a dash panel or integrated into a custom wiring loom without sacrificing underhood real estate. The kit handles both left and right signal circuits simultaneously, managing flasher timing and load balancing to accommodate LED, incandescent, or mixed lighting configurations. By centralizing signal relay and distribution functions, it reduces connection points, minimizes potential shorts, and ensures consistent flash rates across all turn indicators—critical when working with low-draw LED units that would otherwise cause hyperflash or module compatibility issues.

This kit is ideal for custom builders, hot rod enthusiasts, and restoration professionals working on non-standard or extensively modified platforms where OEM turn signal modules don't apply. Universal compatibility means it works across domestic and import platforms—from mid-engine supercars to tube-frame fabrications—provided basic 12-volt DC electrical architecture is maintained. Installation is straightforward for any mechanic comfortable with basic wiring: splice into vehicle ground, battery positive, and existing turn signal switch circuits, then route output wires to your signal lamps. The compact footprint and lightweight construction make it a go-to choice for weight-conscious builds and space-constrained engine bays where every inch matters.
