Yes, that is where I confirmed my calculations but some are not the electronic type so I chose to draw a schematic for him to folow to help make it simple ( I hope).

BTW, I chose not to do it that way because if 1 LED was to fail you then you would have too much current going through the last LED and it would fail as well.

No, because in that aplication you are running the current of both LED's through 1 resistor and in my aplication the resistors are only seeing the current of 1 LED each.

We have a voltage drop across the LED of 3.6V so there is 5.4 volts left to acount for. The voltage drop across the resistor is caculated by V=IR
Voltage = Current X Resistance). With the 330ohm...

Good day!

This should work for you. There are other ways of doing it but this way if one LED fails, the other will still work.

I had a brain fart, you already told me that lol! But I will need to know how many LED's you are going to use. Your picture only shows 2 but are you going to install lights front and rear?

I will need to know what the voltage drop across the type of LED you are going to use or a spec sheet for the led you are going to use (they are not all the same).

Good day!

No, that will not work. LED's need a current limmiting resitor or they will fail as soon as you put power to them. It has been a while but I will try to draw up a schematic for you and...
