Interesting question CLX
Looking at the YMLT plates as an example, they indicate that the HIRL,HIALS and T-VASI are available outside TWR hours. The level of the lighting was set about mid range from memory, okay on a rainy night,but bloody bright on a foggy night. We used the applicable DA as required. The charts appear not to specify the approach light level set, or any restrictions for night use.
It would appear CB is no different to LT, the HIRL, HIALS and T-VASIS for RW35 are available via the PAL when the tower is unmanned.
