there are a few cures.. Most auto parts stores and major truck stops (loves, J, Pilot, TA and so on) sell a Resistor,,, You need at least one per socket if they are 10 watt loads, A turn signal is closer to 25 watts.. And at half wattage the flasher goes fast if it's a standard one
Heavy Duty flashers,, I have yet to test, but I very strongly suspect they will NOT do this,, Since they work on a completly different method.
Here is how the standard mechinicial thermal flasher works:
As currrent passes through the bi-metal bar it gets hot and opens. Then it cools and closes, then it gets hot and opens,, and so on.
How an HD works
The unit starts OPEN.. a small low current wire "heater" is wrapped around the bi-metal arm, and as current flows to the lamps it heats up closing the circuit
Then as it cools it re-opens,, re-heats and re-closes
one lamp (25 watts) or 10 (250) is all the same to this unit.
Solid state flashers... Now those can be designed in many ways,, most of them poorly for LED conversion.
