Narrative:

Refused to operate aircraft with entire overhead panel lights inoperative. Lights would go full bright; dim; and off uncommanded at random intervals. Deemed unacceptable for night flying and totally unsafe for a late night flight to ZZZ with moderate/heavy rain; low clouds and over 20 kts of crosswinds. Refused at aircraft at gate. I believe the MEL that maintenance was going to use was not meant for the entire panel being dark.
