Legacy GT Turn Signal LEDs

3157 Dual-Color 60-1210 SMD is a direct replacement for any 3157-size front turn signal bulb. We sell them with single color and with a "Switchback" option. The "Switchback" is a unique, specialty item. When on as normal, with parking lights, it shines a nice, pure white color, and when you activate the turn signals, it flashes an amber color. Two colors, for an awesome lighting effect!

This bulb has 60 1210-size SMDs. It uses an 3157-size terminal and will fit as a replacement for stock halogen. It uses less power and heat than halogen bulbs, and will last longer, with its engineered heat-sinking technology. A load resistor is embedded to prevent blowing the LED from voltage surge, and a diode is implanted to protect the LED from reverse polarity. The LED is wired for 12v operation, the kind found on all vehicles.

Resistor Option: Some vehicles may have fast-blinking issues when LED bulbs are installed as turn signal replacements. We offer resistors to remedy this issue for a nominal charge. Alternatively, we offer plug-and-play flasher modules to regulate the flashing speed.

We carry the brightest, highest-quality bulbs at the lowest prices. Your order will ship same day, and we're here if you need us for support and service. And we do not raise prices to astronomical levels- We're breaking that market trend, and offering you great, low prices, every day. These LED bulbs are designed by us here in St. Louis, and every bulb carries with it a three-year limited warranty.
