Soldering in LED's, resistor ? Options

[CelicaB]

i did a search but if you want to change climate control light colors ( i know it not REALLY climate control) why do you need resistors? (im electrical stupid) why cant you un-solder the green ones and solder in the blue ones it would make everything soo much simpler than all this talk about running resistors and what not soooo if someone could elaborate on this a lil for me it would be greatly appreciated!

you can solder the indicator leds directly to the board. however the leds to light up the unit would need resistors cause you cant screw them in like the 3 bulbs you are replacing.

here is what to do for the leds that need resistors.

you need to find a power source that turns on with ur lights.
run ur positive from there, add a 220 ohm resistor to the wire then attach the led, now find a negative source and attach it to the negative led strip. you'll find that ur leds will shine really brite. then you can postition them anywhere in the unit you'll have to do this atleast three or four times but you cna use the same source for power.

people will say you dont need resistors... trust me I have done it with and with out resistors. with resistors looks the best.
let me know if you need any help
later
