This horn button assembly is precision-machined from polished 6061-T6 billet aluminum and offers a full-cover design featuring a smooth, plain-top surface. Designed exclusively for nine-bolt Lecarra steering wheels (Mark 4 and Mark 9 series), it completely conceals all mounting hardware beneath its flush dome for a clean, uninterrupted appearance. The single-contact electrical system triggers the horn via an internal spring contact hidden under the button, maintaining a seamless aesthetic.
