I got these turnsignals from Amazon but was underwhelmed by how dim the lights were. They were single element bulbs so I decided to modify them. I removed the bulbs and replaced them with 3157 blade-type LEDs. I straightened the terminals and removed the plastic body. There are four terminals and they are reverseable. The outer terminal is the brighter element, while the inner is the running light. Rather than solder the three wires to the terminals, I used shrink tubing.
Now I have this....
