Product Overview
This high-quality Original Dimmer Horn Switch Assy is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2021-2024) models.
The dimmer horn switch assembly is the left-hand handlebar control unit that houses the headlight high/low beam dimmer switch and the horn button. It provides the rider with fingertip control over lighting functions and the audible warning signal. When the assembly wears or develops electrical faults, the horn may become unresponsive, the headlight dimmer may fail to switch between beams, or internal contacts may become intermittent, affecting rider safety and road legality. This original replacement restores full left-hand switch functionality, ensuring all lighting and horn controls operate correctly on your PCX125.

Complete Part Guide
Your left handlebar switch gear is the primary safety interface for signaling and auditory warnings on a 2021-2024 Honda PCX125. When the dimmer or horn button fails, your ability to communicate with other North London road users is compromised. This original Honda replacement (35200-K1Z-T12) provides the specific plug-and-play wiring needed to restore full control. Stocked at Part Hive's London warehouse; we guarantee same-day UK dispatch for all orders placed before the 1 PM cutoff.
We see these dimmer/horn units fail most often due to internal oxidation or "dead" spots on the contact plates, usually after consistent exposure to the British rain. If you find yourself having to thumb the horn button multiple times to get a sound or if your high-beam flickers when switching, the assembly may be failing. This Original Honda PCX-125 Dimmer Horn Switch Assy (35200-K1Z-T12, 2021-2024) features superior internal weather-sealing compared to low-grade aftermarket versions. Replacing this unit ensures the indicators, high-beam, and horn all operate through a single, secure connection that won't vibrate loose on the Enfield or Barnet dual carriageways.
