Standard Ignition CBS-1839 Headlight Dimmer Switch

The Standard Ignition CBS-1839 is a new headlight dimmer switch built as a combination switch for vehicles with automatic headlights and fog lights. It provides direct control of the main lights, running lights, turn signals, and high-beam functions in one OE-style electrical assembly.

Compatible With select Mazda 3 and Mazda 5 applications, this CBS-1839 switch is a practical replacement when the original column switch becomes worn, intermittent, or unresponsive. It uses a bolt-on attachment method, a female rectangular connector, and 11 male pin terminals for a direct electrical connection.

Detailed Description

The CBS-1839 is engineered for lighting control on vehicles equipped with automatic headlights. It is listed for 2012-2013 Mazda 5 models with fog lights and auto headlights, 2012-2013 Mazda 5 models with automatic headlights, and 2010 Mazda 3 models with automatic headlights. This part cross-references Monroe Shocks & Struts (e.g., BBM466122, DL7239) for the same application.

As a headlight dimmer switch and combination switch, the unit consolidates multiple driver controls into one assembly. The design supports normal headlight operation, high-beam switching, turn signal signaling, running light control, and fog light operation while maintaining the factory-style connector layout used on the listed Mazda applications. The part number CBS-1839 is also referenced as Standard Ignition CBS-1839 for ordering and catalog lookup.

Installation Notes

Install CBS-1839 on the steering column using the bolt-on mounting style and verify connector match before installation.

Always compare the connector shape, terminal count, and switch functions to the original part before replacement.
