• Turn signal control failure at the column switch
• Fog light switch malfunction
• Intermittent running light or headlight control
• Worn indicator markings or inconsistent switch response

Installation Notes and Tips

Verify the vehicle build date and equipment before ordering, since the fitment is limited to 2010 Kia Optima models built to 11/16/09 with the listed options. Confirm the connector style, terminal count, and bolt-on mounting points against the original switch before installation. Because this is a combination switch, transfer only the vehicle-specific electrical connection and mounting alignment checks from the original unit.

Quality Assurance

Standard Ignition supplies this as a new replacement electrical switch for the specified application. The part is built with a plastic finish, blade terminals, and factory-style connector layout to match the original control function on the 2010 Kia Optima.
