LED turn flasher lamps

Good day, folks ?
I've just started changing my rear light cluster to LED bulbs (bulbs go in the ground). And the tail/stop is ok, reverse is ok but when I put the turn/flasher lamp in the lamp holder and fit the flasher unit stops flashing and the lamp just stays on. Now from my point of view it may well be that the load is less and therefore the flasher relay cannot charge the capacitor enough to switch the coil but has anyone had this issue or should I just try another LED lamp. BTW, I also use the LED Series Resistor Calculator to identify the value of current limiting series resistor when driving an array of LEDs, I'm not sure if this calculation is appropriate...I'm not an electrician, so there may be errors.

Has anyone a recommendation for an LED that still looks like a lamp and not a unit with lots of flat LED flat cob dots. Any replies will be appreciated.

Thank you in advance!

  • If you have an old style flasher unit (it sounds like it) you will need the load resistor, and it will be big and get hot. The usual load is 2 x 21W and 6W which take about 4 Amps so a 3.3 Ohm 50 W resistor will be needed. This should work normally, either electronic or bimetal flasher. Ignore the led current (a few hundred mA).
