Transparent Electric Test Pen

You touch the tip to the terminal and the small neon glow answers before you trust the wire.

The body is clear, so you watch the neon element light up the moment the tip meets a live conductor. No guesswork at the fuse box, no assuming a switch is off, just a quick press of the metal tip and a glow that tells you the circuit is hot.

The pen measures 127 mm with a flat blade metal tip, a see through AS plastic handle and a metal cap at the end. The neon indicator sits visible inside the barrel, and the tip doubles as a light flat screwdriver for the terminal screw you are already touching.

Key Benefits

• Neon live indicator The neon element glows when the tip touches a live conductor, so you can tell a hot wire from a dead one at a glance.
• Tests 100 to 500 volts The range covers household outlets, switches and terminals across common mains voltages.
• Transparent body A clear AS handle lets you see the neon light and the internal parts while you work.
• Flat blade tip The metal tip meets terminal screws directly and doubles as a light flat screwdriver.
• Hard wearing build A hardened metal rod, an AS plastic handle and a neon element made for a long service life stand up to daily use.
• Pocket length At 127 mm it clips into a shirt pocket or a tool roll and rides along with your other testers.

Best for: electricians and DIY hands who need a fast, pocketable way to check whether an outlet, switch or terminal is live before they work on it.

Why It Works

A multimeter tells you a number but takes two hands and two leads. This pen answers one question, is it live, with a single tip and a glow you can read in a crowded junction box, then goes straight back in your pocket.

Quick Product Facts: neon voltage tester; range 100 to 500 volts; 127 mm long; transparent AS plastic handle; flat blade metal tip; metal end cap; model options YT-109, YT-168 and YT-868 with copper or plastic cap.

How It Fits Your Routine

Before you loosen a terminal you press the tip to it and read the neon, confirming the breaker you flipped actually killed the circuit rather than the one next to it.

Around the house it settles the small questions fast, whether an outlet is dead, which switch feeds a fixture, whether a wire in the wall is carrying voltage, then clips back into the drawer.

FAQ

How does it show voltage? You touch the metal tip to a conductor and hold the metal cap, and the neon element glows if the point is live.

Does it need a battery? No. The neon indicator lights from the voltage it is testing, so there is nothing to charge or replace.

What voltage range does it cover? It reads live circuits across roughly 100 to 500 volts, which covers common household mains.

Can the tip turn a screw? Yes. The flat blade tip works as a light flat screwdriver for the terminal screws you are already testing.
