I recently installed a set of Abstract Ocean puddle lights, I highly recommend them. This left me with two unused LEDs and I thought I might as well mess with them. I popped one open and they are just a single LED on a board. Wiggle the board up and down by the end opposite the metal connectors. The board pops right out and leaves the two pins behind. I had a roll of LEDs left over so I snipped out a three LED section and soldered them to the post. If the pins are on your left the pin closet to you is negative. My strip was a little long but it’s fexible so it’s easy to wedge in there. It’s ugly but once you pop the cap back on it looks perfect. Each LED is much brighter than the single LED in the original and now you have three. They even work in the foot wells. I think a roll of 12v LEDs is like $15-20 and that is enough to do at least 20 cars so your a few cents per light. I only did two so far took me about 10 minutes. The strip I have is warm but I prefer cool so I need to grab another strip. This is the board popped out.
