Hello,
I am looking into build my own LED Cluster, to replace the standard bulbs in my car.
I have come up with a design for my PCB, but I wanted to run things past some of you guys here so as not to risk setting fire to my car as such.
The cluster involves 8 0.5w LEDs connected in paralell as two rows of 4 LEDs. I am unsure of how many resistors I should use, whether I can use one per the whole PCB or, whether should be 2 resistors, one for each row of 4 LEDs, or even a Resistor for each individual LED.
I am also unsure of the resistor rating I should use for my circuit, the car obviously runs on a 12v circuit, the bulb it would be replacing is a standard 21w 581 bulb.
I am then wondering how I should do the stop/tail light bulb, could I run one circuit through the resistor as the circuit above, and then the other circuit will goes through an extra resistor? ie: Tail light circuit 2x resistor, Stop light circuit 1x resistor.
Thank for reading, very much appreciate your thoughts!
