Experiencing a faulty circuit but don't know what's causing the problem? These red LED pilot lights from the RS PRO range have an extra terminal, so you can connect them to lamp-test circuits and locate the source of a malfunction.

They use multi-chip technology for a strong glow and steady colour. At ≥60 cd/m³, they're brighter than standard incandescent bulbs and can be seen in all light conditions. With a lifespan of up to 30,000 hours, you get a long-lasting product in a space-saving 22 mm cutout design. They have an IP65 rating, which means they're protected from dust and low-pressure water jets. This pilot light complete with test circuit can be panel-mounted for easy installation on most surfaces, and captive screw-clamp terminals mean you can connect wires without soldering.

While these lights are ideal for testing circuits, they can also be used as normal LED pilot lights. You'll find them useful for anything from aircraft instrument panels to kitchen appliances.
