While landing on Cancun (MMUN) Airport Runway 12R at night we noticed that many of the signs along the side of the runway and taxiways were not illuminated. We were not sure of the cause:1. Tower forgot to turn sign lights on?2. Sign lights worked at one time; and do not work now?3. Sign lights never worked?It is much easier to identify an exit taxiway from the runway and judge the proper braking required at night if all the signs are properly illuminated after sunset.1. Sign lights need to be inspected on a regular basis to ensure the sign lights are illuminated at night.2. Institute fail safe procedures in the Control Tower to ensure sign lights are turned on each night.3. Repair sign lighting system to ensure that the sign lights are operational.
