Review on IBrightstar Switchback Projector Replacement Daytime by Ken Lawson

These bulbs have a different socket than many other 3157 bulbs I own. It's not that deep and doesn't have a latch. I was able to get the bulbs to light up by changing the connecting wires, but they don't stay in the socket. Update 05/06/19: I received an immediate request for information from the granary and am therefore changing my rating. The user manual says 3157, but after searching the web a bit I found a link to my specific setup which said 7443. The company's response was very timely, helpful and helped resolve the issue. Thanks granaries! Now that I have the right bulb I can say that the intensity and the switch back function are fantastic.
