I found the dash lights pretty useless during the day time on my 81 G5, which I believe has a similar dash as yours. I decided to get LED bulbs for the dash turn signal indicators only however, and that's my recommendation. If you upgrade the others to LED it might just be "
too much light shining in your eyes at night. Some upgrade them all, so that's a personal preference.
Things to know. Best to use the same color LED as the lense its to shine through (green/green)
Also, if upgrading the whole dash, leave the generator bulb factory as the LED might cause the charge circuit the not charge properly. However, someone here just did put an LED in the position and the charging still works, so at least know that if you do change it to LED be sure to verify if the bike charges or not.
The upgrade on the dash turn signals was a huge improvement. It's like day and night ;-)
I can post the part number later if you can't find it.
