2 Volt LED Panel Lamp for 1/4” hole size. Considered the “universal” type as it can be used with virtually any DC voltage with a resistor (package shows how to determine resistor value). And it can be used with AC voltages with a diode and resistor. The lamp has 6” long wire lead set (black / red), which is stripped and tinned, ready to solder. Body color black (nylon).
