LED lighting question

Just purchased brake, turn, and reverse light leds from superbrightleds.com. (Never installed them before on a vehicle). I know I have to purchase some resistors but not sure if I need 1 resistor per bulb so 3 resistors per tail light housing or 1 resistor per housing? So 1 resistor for all 3 bulbs? Is it okay and safe to do all 3 bulbs in ea housing or would it be better to just replace the 2 brake light bulbs with leds and thats it? Any info and tips would be greatly appreciated.

 

Just get an electronic flahser yo! I don't think you need a resistor for anything but the turn signals. I may be wrong on that though. But I'm pretty sure you don't. But for the turn signal, the electronic flasher is the way to go. Just pop it in and done.

 

My LEDs (reverse, liscense plate, and interior) were all plug and play.

 

Ok. Now my truck being an '03 would that matter? And thise are all smaller bulbs. The brake and turn signals are bigger bulbs. I just don't want hyper flashing or problems with my cruise control.
