HI .
I have 12 superflux leds in my car headlight in paralel with 12 ,180 ohms at 14 volts.
Each led has a resistor on them . The superflux led is a 7500k at 3.2 volts and 80ma 1watt for 12&14volt and 0.5watt or 9 volt .Now I had then in the headlight for the summer and they are great , and now that it is colder (45 degrees) the leds are starting to burn out. Now I realized that the leds might not be getting a steady 14 volts from the car ,the voltage keeps going up and down from 10 to 12 to 14 to 13 (get what Im saying). Do I need a voltage regulator to keep the voltage steady and if so what type and at what voltage is good 9v or 12v , and will I have to put 1 on each led or can i just use 1 for all.............
I know there are good tech out there please I need some information
THANKS
