Here’s a post I made about my conversion to LEDs. (
https://www.lotuseuropa.org/LotusForum/index.php?topic=891.msg6614#msg6614) I did it a long time ago so there you may be able to get them all from supergrightleds.com or other supplier. If you’re going to convert your idiot lights (turn signals, ign, bright, etc.) I found that my car had two different bulb bases so you’ll have to investigate them yourself.
If you end up converting your turn turn signals, you’ll need either electronic flashers or resistors at each corner. Most flashers are silent but I found some flashers at Amazon that do make a sound. They beep rather than click so it can be a little off putting if you’re not used to it. For that reason, you might opt for the resistors.
