Replacing car turn signal bulbs with LEDs can be a bit of a hassle, if the car expects a regular bulb it will flash rapidly (LEDs draw so little power car 'thinks' it is like a blown bulb).

The 'hyperflashing' can generally be fixed with a load resistor, which basically just wastes electricity to simulate a traditional bulb.

No need in NA Miatas though, one little resistor change ( replace R1 with a 1M ) in the flasher unit is all it takes!
