Many cars still use incandescent indicator lamps, and relays to flash them on and off.
LEDs powered by switch mode led drivers are not wanted for car indicators because of the repetitive inrush that you get into the input filter capacitance of a switch mode led driver's input capacitor. -So its either relays flashing incandessant lamps, or relays flashing leds powered by linear led drivers (linear led drivers have very little input capacitance).
is this true that switch mode led drivers are no good for car indicators (turning indicators)
