test light correct use

    Question regarding video "Basic Electrical Review Part 1" under Basic Electrical Concepts folder. Time stamp 38mins - 39mins Paul covers using test light to energize control circuit of relay. I did the same test externally (as show in attached image) to practice using an incandescent test light to activate coil in a relay. But my test light bulb lit very dimly and coil field did work as relay did click. Why is that when Paul uses test light to energize coil in video, the light bulb in test light doesn't light up? isn't there current flowing thro the test light at that point in time when he is activating the relay coil?
