Hi. I'm thinking of doing the same to my headlights but my numbers indicate that I should be using 200 OHM resistors at 1 watt. The LEDs are runnung at 26mA not the 20mA that they are designed for so the current draws .762 watts. Therefore you should us at least a 1 watt resistor not 1/4 or 1/2. My numbers are as follows: 12 v devided .060mA (3 leds in series) = 200 ohms. Please let me know what you think. I just do not want to be opening these headlights once a year. The way I see it the current is greater than the resistor can handle and they may burn up.
