Quoted from kcZ:I was disappointed at first when the lights did not work but then I swapped the wires and it works. I used standard bayonet sockets with a flex bulb led in the middle of the switch slot. Wired this to each of the insert lights. I have a Met Prem, btw.
And you soldered to the tabs on each board, right?
Nah, I just went down and triple checked, just so I know I'm not crazy. Switched wires back and forth and tried multiple bulbs. Do you have a metal backbox led run premium?
