Detailed Description

The CBS2405 is a replacement combination switch built for Lexus vehicles that use a headlight dimmer switch integrated with turn signal and fog light controls. It is listed for 2013-2017 Lexus GS350 and GS450h, 2014-2015 Lexus IS250, 2014-2017 Lexus IS350, 2016-2017 Lexus GS200t, IS200t, IS300, RC200t, RC300, and 2015-2017 Lexus RC350 applications. This part number, CBS2405, also cross-references Standard Ignition CBS2405 for the same application.

Use this switch when the original lighting control assembly has worn contacts, intermittent beam selection, or damaged indicator markings. The design includes the main light operator, latching high beam function, fog light operator, and turn signal control in one assembly for supported Lexus GS, IS, and RC models.

Common Issues This Part Can Address

  • Headlights not switching correctly between low and high beam
  • Turn signal control problems at the steering column switch
  • Fog light operation failure on equipped vehicles
  • Worn or faded indicator markings on the switch face
  • Intermittent lighting control caused by internal switch wear

Installation Notes and Tips

Verify the vehicle is equipped without daytime running lights and matches the listed fog light configuration before ordering. Confirm the connector shape, terminal count, and attachment method against the original switch before installation. Because this is a steering-column combination switch, careful alignment during replacement is important to preserve proper lighting and signal operation.

Quality Assurance

Standard Ignition supplies replacement electrical components for service applications, and this CBS2405 switch is new, not remanufactured. Always confirm fitment by year, make, model, and equipment details before installation.
