The most common issue is with fitting new bulbs to new or used socket strands. They often require a bit of adjustment - much like breaking in a new pair of shoes. The most common adjustments are:
- The pin on the side of the socket needs to be pulled out just a bit so that it has a snug fit with the side of the bulb base.
- The pin in the bottom needs to be pulled up just a bit in order to make solid contact with the bottom of the bulb.
- Some third party brands of socket strands (particularly GE branded strings) that have a small lip on the top inside edge of the socket that needs to be ground off in order for LED retrofit bulbs to properly fit into their non standard socket base.
