Dash Cluster Bulb Replacement

Hey All,

New owner of an 84 Honda Interceptor VF500F. Everything on my dash cluster is working great except the signal lights. The actual turn signals themselves seem to work just fine, but the indicators on the dash do not. I figured it would be best to start by replacing the bulbs and if there is a wiring issue maybe I would happen upon it.

Any advice on how to do this out there? What kind of bulbs do the turn signal indicators in the dash cluster take?

Thanks
