Hoping I can get some help. I have a Seagull Address Light model 9600-821. From what I can tell by the label on the unit, it's a 12V 5W. It's old. I tried replacing with a Seagull Address Light that is LED and 120V (model: 96091S-12). I connected the white wires and black/pink wires together using electrical caps/wire nuts and the light won't turn on. Am I wrong to think a 120V LED will work on lower voltage? Wires are connected to a transformer as it's connected to the doorbell. What are your thoughts?
