MEL
Assigned this aircraft and saw that it had 12 MEL's with one additional open item forthcoming according to ramp maintenance. Capt and I reviewed the MEL's and could comply with each MEL on the flight tonight. Concern was at what number of MEL's does it become too much and the jet become down until they are fixed. Capt had flown with an FAA maintenance inspector previously who informed him that generally speaking it would be 5 to 6. We consulted with our dispatcher and the Duty Officer over our concerns. We knew we could safely execute the flight while satisfying all MEL requirements so we proceeded to fly the aircraft as scheduled without any incidents other than identifying the right hand turn off light while working appeared to be misaligned and of little use to the Captain but did assist myself looking out to the right side of the aircraft. During flight the Captain sent an ACARS message to Maintenance and wrote this up making the total MELs now at 13.
MD11 First Officer reported accepting the aircraft and flew with 13 listed MELs.
