Narrative:

We were climbing through 4000' when both engine fire lights illuminated in the cockpit. The engine fire in-flight checklist was called for and then we declared an emergency with seattle departure, and requested radar vectors to return back to the seattle airport. They gave us radar vectors for a visual approach to runway 16R backed up by the ILS for 16R. The passenger were then notified about the emergency. We got the airport in sight for the visual and landed on runway 16L. After landing we taxied off the runway and the emergency equipment looked over the aircraft and determined no indications of a fire, we then fired the fire bottle as a precaution. We taxied to the gate and disembarked the passenger. After the passenger were unloaded, myself and the emergency crews looked over the aircraft again to check for indications of a fire and found no indications.
