LED Switchbacks take signal lights to the next level. They come with dual filaments that allow you to change between two light shades— amber as well as xenon white. Compare this to the halogen turn signal bulbs that we are all used to. They allow you to change from low-intensity parking lights to high-intensity lights.
One may also ask, how do switchback LED bulbs work?
Switchback LED bulbs are a unique way to upgrade your lighting! In a dual filament socket, they will light up with white color as the low-filament running light, and switch to bright amber any time you hit the turn signal. When you switch the turn signal off, they'll "switch back" to white again.

Hereof, what is a dual function LED bulb?
Overview. LED replacement bulbs can fit vehicle tail lights, brake lights, reverse lights, turn signals or side marker lights. This 3157 dual-contact, dual-function bulb has 18 LEDs (5050 SMD) that create a 360° viewing angle for better, allover light emission with reduced hot spots.
What is switchback DRL?
When you start your engine the white LEDs come on giving you another set of daytime running lights. When you use a turn signal, the side you're turning to reverts back to a flashing amber. When the turn is finished and the signal cancels the light goes back to white. Magic!

- 💡【Load Resistor】Few vehicles may have hyper flashing because LED draws much less power and lasts longer than stock incandescent lighting. Although the reduced draw of LED has advantages, replacement of turn signal bulbs with LED may cause hyperflashing. This happens because your new LED bulbs draw such little power that your turn signal relay sees the bulbs as being out.if your car has flashing, pls add 50W 6-Ohm load resistors or flasher relay.

Believe it or not, LED lights have a lot in common with sunlight. LEDs can mimic the hue and intensity of natural sunlight and help to maintain the human body's natural circadian rhythm. This is because LED components allow for finer adjustments of color, brightness and intensity.
The three primary types of color temperature for light bulbs are: Soft White (2700K – 3000K), Bright White/Cool White (3500K – 4100K), and Daylight (5000K – 6500K). The higher the Degrees Kelvin, the whiter the color temperature.
