Wiring L.E.D. within parallel, I still entail resistors right?

Im want to add some L.E.D.s to my saloon, and I wanted to do it within Parallel, I know in speakers it reduce the impedence of them. I was wondering if it have some kind of similar effect for lights, or if its basically a straight wiring and adding together a resistor to each of the LEDs. (12v coup¨¦ battery beside 470 Ohm resistors for Blue LEDs)

Answers:    Yes, you do. LEDs, being a diode, the voltage drop across it will be a constant 0.7 volts. (not same for the speakers).

You will inevitability to make sure, your register can bar DOUBLE the current passing through it, but i.e. about the simply change.

What I would do, is to receive the additional LED near its own resister and parallel that assembly to the existing one. (that is, instead of just paralleling the LED and use the existing resister)
