I replaced all of mine with bulbs from superbrite. I used the amber version of the blub for the turn signals, blue for the highbeam, red for the oil, and warm-white for the headlight indicator (if your bike has that). WLED-A5, WLED-B5, WLED-R5, and WLED-WW5. Of course green for the general gauge lights and clock. WLED-G5 and 74-GHP (clock). Maybe one day i'll get around to changing all of the running lights and brake lights. Probably will need a digital flasher module then.
Here is the webpage for the dash bulbs:
