2- prong LED Flasher recommended for Classic Auto LED Tail Lights
LED turn signals usually require an updated flasher to work properly. Most flashers require a minimum of 2 or more incandescent bulbs to flash correctly. That is 3.5 to 4 amps for proper operation. An incandescent turn signal bulb uses about 1.8 amps while an LED turn signal uses 0.25 to 0.45 amps. One incandescent bulb and one LED turn signal don’t draw enough amperage for the flasher to work correctly. They usually will turn on and stay on.
