Narrative:
Deferral stated EICAS message engine anti-ice displayed and engine anti-ice valve light remained illuminated with switch on position 2. Action-verified; valve operations normal; reference MEL chapter 30-21. Item deferred for time per maintenance control. Defect: right engine anti-ice valve light inoperative. I was suspicious of the deferral.reviewing the write up; this doesn't look like a simple light inoperative. No time to replace a light bulb? To me this looks as if the valve was indeed inoperative; not the light; and we were going to ZZZ which was experience icing conditions.I refused the aircraft and then indeed the valve was replaced; not the light; which was working properly. Frightening to think what cursory review write ups receive; and what the consequences of improper deferrals could lead to.
