I used LED's from a place called superbrightleds.com. The dash LED's have the same shape as the originals. I got blue ones for the dash lights & high beam, red for the brake warning, and amber/red for the rest of the running lights. Very happy with the results. Had to get a different flasher (one with a ground wire) because the flashers that company sold did not work for my duster. Again, very happy with the results. Nice and bright, and are dimmable if you want less light.
Edit: Be sure to test before putting your cluster back in. LED's are polarized, so they will only illuminate if they are installed a certain way. Just take the socket out, twist 180*, and put it back in. For the front parking lights, I had to cut the wires going to the socket and reverse the connections. All good now.
