I bought a couple of these and installed one. It went in very tight and I had to push it somewhat to get it in. I then tried to uninstall it and reinstall the original bulb. When I did, the original bulb no longer made good contact. It was sloppy and no longer held tight by the wire grabbing type socket. It seems that the wire gauge on this upgrade must be heavier than the original bulb and that when you install the LED, you damage the wire contacts enough that you cannot go back to the original bulb. Anybody else experience this?
