Clock bulb is Honda part number 35505-S84-B02. You can pick it up from your local Honda dealer. You can literally pull the clock assembly out with your hands, then disconnect the electrical connectors and replace the bulb.

See TSB and internet dealer description:

I believe the odometer bulb is a #74, available at most auto parts stores.
