The sense resistor measures the current by building up a proportional voltage:
V = I * R
A working system needs to produce about the same voltage, otherwise the blinker goes into hyperflash to warn you of a dead bulb.
The LEDs draw about 1/4th of the current (I) So, to keep V in the same ballpark, R needs to go up by a factor of four. I decided to be conservative and only go up a factor of three. That turns out to work for any combination of LED or incandescent bulbs.
Measuring 0.02 (or 0.06) ohms is not that easy, the test leads for your multimeter will have more resistance than what you are trying to test A special 4-wire (Kelvin) test cable is what is normally used to get around that problem.
