I want blinking coils! COP.

[DreamV4]

Tomorrow I will get ordered 2.2 Ohm resistors and install them instead of bulbs on COPs. But I still want Christmas tree (most likely GoldWing disease). Any ideas which LED and resistor? Any smallest LED and resistor (about 300 Ohm or so) will do. I don't think it will cost more than $5 for all 4.
Following these steps to calculate resistor value for LED Lighting by 12V, DC:

1. Determine the voltage and current needed for your LED.
2. We’ll use the following formula to determine the resistor value: Resistor = (Battery Voltage – LED voltage) / desired LED current.
3. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/.010=860 ohms.
4. To use several LEDs in parallel, sum the current values. From the example above, if we use 5 white LEDs the current requirement is 10mA x 5 = 50mA. So (12-3.4)/.050=172 ohms.

unless we know where in the circuit you intend to fit the LEDs and drop resistors, the above calculations aren't useful.
