As some of you may know I converted all the interior lights in my X to LED. I have about 30 LED's left with resistors, so I converted my puddle lamps to LED. The Ford Five Hundreds each have 1 LED in their puddle lamps, so I used 3. All I did was cut the + wire at the bulb holder on each lamp, wire a leg of a resistor to each, then taped it up. Next I took 3 LED's per side and twisted the corresponding legs together. I put some tape on and plugged them into the bulb holder. They lit up! Put everything back together and now I've got some pretty bright puddle lamps. The first picture is the Ford Five Hundred $25 LED (RIP OFF), second is it lit up outside of the lens, third is my finished product of 3 LED's. Not too shabby!
