Put your turn signals, headlights, and high/low-beam control back in working order with the Standard Ignition Combination Switch HLS-1190. It's a direct-fit replacement for the 1999-2005 Mazda Miata, mounting on the steering column to operate the vehicle's lighting and signaling functions. Because this part is cataloged under several names, you may see it listed as a Headlight Dimmer Switch / Headlight Switch / Turn Signal Switch.
- Multi-function control: handles the headlight dimmer (high/low beam), headlight, and turn-signal circuits from one steering-column switch.
- Direct-fit application: designed to replace the original switch on the listed Mazda Miata models.
- Signs it may need replacing: turn signals that won't activate or self-cancel, high beams that won't switch, or intermittent headlight operation.
If a failed combination switch is the cause of these symptoms, installing the HLS-1190 replaces the worn unit; diagnose the circuit first, since wiring, bulbs, or relays can produce similar signs. Always confirm the switch is the fault before ordering.
