I used mainly 3mm blue LED's with resistors, Not sure which ones exactly I used seeing as it was 2 years ago. Then i used 5mm LED's for the door switches. And for the DIC i used a 3 - 4 wide FLAT LED's. The DIC is the hardest part because you have to pull part the screen and remove the red film and put in a white film (piece of paper) and then solder it back together. Then change out the bulbs with LED's.
