Turn signal switches are used for standard applications such as right/left signal indication, but some available styles offer other functions as well. Other functions include: hazard/warning lights, flash-to-pass, marker lamps, and even slide switches for wiper control. All turn signal switches available have an 18-bulb capacity, making them an ideal use for a triple trailer. Several styles will also adapt to applications without brake override functions. Current selection includes Universal replacement styles and OEM-Styles as well as variations of those.
