Switchback LED BulbsSwitchback LED lights are also known as dual-color LED, which are dual-function LED bulbs or LED strips that stay lit as xenon white in parking/position light mode and flash amber when the turn signals are used. These are specifically designed for front turn signal lights or daytime running lights.

iJDMTOY is the very first company to invent this two-color LED products now carries this kind of switchback LED in many different sizes such as 1157, 3157, 7443 and even carries a retrofit type of single filament 7440 as well as switchback LED strips and daytime running lamps for car front end customization.

This kind of switchback LED will give you a nice HID-matching look when operating as the parking lights and are legal since they flash amber when the turn signals are used!
