Description Our 4-LED unit has four high-brightness, high-quality LEDs attached to a single joint with two lead wires ready to connect to your power source. For the 5mm, 3mm, and 1.8mm LEDs, there is an 8-inch wire to each LED from the circuit, giving you ample space to separate your LEDs to light more space with fewer wires to connect. For the Mega, Chip, Nano, and Pico size LEDs, there is a 3-inch wire to each LED from the circuit, since these are meant for use in smaller-scale trains or models, and lots of excess wire can be a hassle. Choose from three different voltages: 3 volt, 5-12 volt, or 7-19 volt AC/DC/DCC. Every unit is pre-wired to the proper resistors. The AC/DC/DCC option also has the proper bridge rectifiers, so they are ready to hook up to your train transformer or other 7-19 volt power source. You have a choice of either cool or warm white. Our wide selection of battery holders means you can have more flexibility with your layout. This is a great bright way to add nice bright light to your model trains, passenger stations and buildings, or your own ideas! These micro LED lights are ideal for projects that require a lot of illumination but very little space for installing lighting. Popular among our modelers, miniaturists, and dollhouse customers, the flexible and thin magnet wire allows customized placement for each LED with up to a maximum of 16 inches between LEDs.
