This magnetic LED light works great when attached to any metallic surface including the area around the needle bar.  The 6 LED lights flood the sewing area with enough light to help you sew with ease.
The light has its own on/off switch that allows you to turn off the lights if you wish. 
With Titan TN-550W/750W motors, they have a 110V plug in that allows you to keep the light plugged in and turned on all the time.  When the motor is turned off, the light is turned off.
