This tiny but mighty dashboard light from Painless Wiring is perfect for custom dash panels, warning indicators, or accessory lights in your car, truck, or boat. It's a 1/8-inch (0.3 cm) diameter red indicator light that operates on 12V DC. The design is simple: it fits into a small drilled hole and typically has a snap-in or screw-on retention ring. Painless is known for high-quality, American-made products, and this light is no exception—it's built to last with strict quality control. Use it to indicate when an accessory is on (like off-road lights, a fuel pump, or a cooling fan) or as a low-oil or high-temperature warning. Installation is straightforward: connect the wires to a switched 12V source and ground. It's a small part, but it adds a professional, functional touch to any custom wiring project. Reliable, bright, and made in the USA.
