An orange blinking light on a Nintendo DS typically indicates that the system is in sleep mode or that the battery is low. If the light is blinking while the device is on, it may suggest that the battery needs to be charged soon. To resolve this, connect the DS to its power adapter to recharge the battery. If the issue persists, it may require further troubleshooting.
