I'll assume you're talking about the speedo, rpm, and gas gauges.
No. The LEDs that are used in the gauge cluster are small and square. Look in the install section for pictures. If you just go to Radio Shack and buy some "LEDs" they will not fit because they are the standard round ones. The connection points are completely different. I don't think the round ones would fit in that tight of space even if someone did manage to put those on.
yeah it depends what "regular LEDs" are. if they are the big ones that have a fatty "bulb" at the middle then no. the LED for the cluster are small and rectangular
