    How do I wire LED turn signals to turn signal switch 48272? The original switch will flash LEDs, but the 48272 switch is just steady on, no flashing.

    Grote's Answer

    It is important to know the min amp draw of the flasher being used. An LED lamp on ‘turn’ function draws appx 10% of what an incandescent in the same application would draw (250 milliamps vs.  2.5 Amps).

    Original Equipment flashers will all have a minimum amount of Amp draw to make them open and close, so they are not operating all the time. Typically that is 2 Amps, but in some newer versions it is only 1 amp.

    If you change only the rear lamps to LED the flasher will think you have a lamp out and will begin the rapid flash. If you change all lamps on the turn circuit to LED, you will need to install Load Equalizing Resistors on each side.
