How do i wire LEDS to a 12v supply

I've got some LED lights that used to work of 6v a battery, 60 LEDs per light, I want to convert them to use 120 LEDs to run of a 12v system, i've got 1,5ohms and 2,9ohm resistors that came with the lights, how do i wire them to work? Might want to put 180 LEDs per light if it works, i've already burned 120 LEDs

Paralleling LEDs is a bad idea. I'd put a resistor, and three in series, for 20 times to get a good result.
The best way is to know the forward volt drop off the leds. White ? Guess at 3 V

Yes white, do i put the resistors in serie or parrelel

Most websites suggests that it is around 3 v
If i use double the amount of resistors used in the 6v system, wire them in parrelel, could that work?
