Next time you're in JoAnn's or Michael's go to the floral department. They have little LED lights that are about 1" square and give an amazing amount of light in a concentrated spot. They are meant to put in floral displays and can be used in water. I stuck one right down at the base of the machine arm to shine on the needle. These lights are disposable, come in colors but for this purpose I bought white. There's a little tab on the side to turn it on and off and it seems to last for a long, long time.
