This is a course designed for Deck Officers to practice the skills needed to successfully complete the practical flashing light requirements for Visual Communications (Flashing Light).

All students are required to set the final exam at either a Prometric Testing Center within the United States or at the Calhoon MEBA Engineering School.


Prerequisites: None

USCG Approval: Any applicant who has successfully completed the Visual Communications (Flashing Light) (On-Line) (MEBAMD-728) course will satisfy the Visual Signaling training requirements of 46 CFR 11.309(a)(4)(vi) and 11.319(a)(4)(vi), if the course completion certificate is presented within 5 years of the completion of training; AND will be considered to have successfully demonstrated the equivalent of Tasks 8.1 and 8.2 in NVIC 12-14 (Ch 1) for an STCW, as amended 2010 endorsement as Officer in Charge of a Navigational Watch.

While classes are scheduled in specific increments, students will work at their own pace.  Working within the time frame of the course, students are free to use the entire time allotted if needed, or to complete the coursework more quickly.  Though students will work at their own pace, they are expected to complete all assignments and, when required, to interact with the instructor.  Additional course-specific information will be sent to students upon successful registration into a class.

Students may register for more than one class in the same time period - however, please remember that a separate application form is needed for each class.  More detailed information is available on the admissions pages for online courses.


All students taking CMES online courses are required to take the final exam at a Prometric Testing Center in the United States, Guam, Puerto Rico, or the US Virgin Islands. After all coursework is completed, the student will be provided with the necessary information and authorization to schedule the final exam at a Prometric office location that is convenient to him or her.

  • Testing MUST be scheduled and completed no later than 30 days from the date that CMES contacts the student with authorization to test at Prometric.
  • The course certificate will be mailed to the student within 10 business days of successful completion of the final exam at Prometric, to the student's address of record at the time of course registration.
