Horn Button Assembly – Plastic with Polished Aluminum Cover (Single‑Contact, GM)

This horn button features a polished aluminum outer ring over a black plastic base, designed for use with Lecarra nine-bolt steering wheels on GM vehicles. It uses a single-contact horn circuit that completes the electrical path through a hidden spring beneath the surface. The design remains flush with the wheel, and the visible exposed screws around the perimeter secure the assembly in place—this is a standard cover, not a full-cover design. It provides a classic look while delivering reliable functionality.
