Welcome to the forum Gyro!
I will answer one of your questions. Yes, it is not unusual for the indicator bulbs to burn. I had to replace a number of mine several times on my 2005 before I replaced them with LED's.
Checking these bulbs is super easy. The plastic housing which covers these bulbs is held on with two screws. These screws are very small and easy to lose, so be careful not to drop these. Just loosen both screws and try to pull the housing and screws off together. With the cover off, check to see if these lights are working. If not, the indicator bulbs can then be removed by pushing down and turning them counterclockwise. Then you can check the filament to see if it is broken or you can use a continuity tester. If your high beam indicator or turn signal bulb works but not your neutral light, then move one of the working bulbs into the neutral light socket. If it still doesn't work, then the problem is something other than just the bulb.
I hope this helps,
