Only 1 of 2 packs works as described. Only one lamp lights up on the defective splitter. Tried 4 different bulbs and 2 different sockets. 1 works fine but on the 2nd only one light is on. So not a good price when you have to buy 2 to have one that works. Update (a few days later) - I was about to throw out the faulty socket and took a close look at the 2 connector plates(?) in the non-working socket. I don't know what they're technically called. They looked like they had been inserted almost flat so I pulled back/bend them a bit to make contact with the bulb. I screwed in 2 lightbulbs and screwed the splitter to the socket. And so! Both lights came on and stayed on! Glad I didn't throw it away. Upgrading my rating from 3 stars to 4 stars only because I had yet to go through all this to get the splitter working and almost threw away his perfectly working splitter because it didn't "work" to begin with.
