Switchback LED bulbs provide a unique way to upgrade your vehicle’s lighting. Using a dual filament socket, the switchback LED bulb lights up with white as the low-filament parking light and switches to bright amber anytime you toggle that turn signal. When you’re done turning, and the signal lever is back in the center position, they will “switchback” to the white running lights again.
What vehicles can 1157 Switchback LED bulbs be used in?
LED switchbacks come available for any type of vehicle but only work for dual function lights that have both the parking/city light and turn signal function in one bulb.
White for DRL or parking lights; Amber yellow for turn signal lights. By utilizing the color change of "amber-off-amber-off" when you turn, you provide other motorists with better visibility of your turning intentions and react as quickly as possible. When you drive straight, you also have clear and bright white light, which again makes your truck easy to spot in dim surroundings.
Each 1157 switchback led bulb is equipped with 16 pieces 3030 SMD chips, 360° lighting, no dark spots or shadow areas, protected with HD glass lens for stronger light penetration and maximum light output.
