Used these in several Mopars. They plug right in and are dimmable via the stock headlight switch. Use same color LED as the lens in the dash

I used these in my 1970 Monte Carlo as well, plug and play with nothing additional. They dim, but a bit "choppy" compared to standard bulbs. They don't dim smooth, but do dim. Once they get so low, they turn off vs barely on like standard ones. Not sure if that explains it. I will see if I can get them to load onto youtube and share a link.
