The Multicolored Alligator Lead Set by United Scientific is a pack of ten 14 in test leads made from 22-gauge braided copper wire with flexible PVC insulation. Vinyl-sheathed alligator clips open up to 0.5 in, and the leads come two each in red, white, black, green, and yellow for color-coded wiring. Teachers and teaching labs use them to connect batteries, bulbs, switches, and meters in electricity and electronics experiments.
