Measuring the voltage at an empty bulb socket just shows the voltage without load. It doesn't tell you the voltage under load (which is the voltage while the bulb is running), and it doesn't tell you where any loss may be occurring (the feed side or the ground side).And what do you mean I can't use a multi meter in my bulb socket to check voltage? That makes no sense to me as probing wiring and sockets is a huge part of my job, you're saying those voltage readings are fake?
The method described on this page (scroll down to "How to Measure the Voltage Drop") shows how to check the voltage while the bulb is in place and will help you determine where any losses are occurring.
