Detailed Description

The CBS-1826 is a combination switch that consolidates multiple driver controls into one steering-column-mounted unit. It includes turn signal control, main light operation, running light operation, fog light operation, latching high beam control, and momentary high beam flash function. This makes it a direct-fit electrical replacement for Kia Optima models that use the specified lighting and headlight-control configuration.

This part cross-references Standard Ignition CBS-1826 for the same application. For Kia Optima repair work, it is a practical choice when the original switch has worn contacts, inconsistent beam selection, or failed lighting control functions.

What It Helps Fix

• Headlights that do not switch correctly between low and high beam
• Turn signal operation that is intermittent or nonresponsive
• Fog light control issues on equipped Kia Optima models
• Running light or main light switching problems
• Worn steering-column switch feel or electrical contact failure

Installation Notes and Tips

Verify the vehicle’s lighting configuration before ordering. This part is listed for 2006-2011 Kia Optima applications with automatic headlights, and select 2010-2011 vehicles with fog lights. The switch uses a single rectangular female connector and bolt-on mounting, so connector shape and terminal count should be matched to the original unit before installation.

Confirm the existing switch functions, including fog light and auto-headlight equipment, to ensure the correct Kia Optima replacement. Standard Ignition CBS-1826 is intended for vehicles with the listed electrical setup and should be compared against the original part number and connector layout during service.

Quality Assurance

Standard Ignition supplies replacement electrical components for vehicle-specific applications, and this switch is built as a new part for direct replacement use. Interchange references include 1S11440 and 53-59064 for the same application family.
