Brüder Mannesmann M1130 auto-spanningsmeter testlamp 6-24V DC

The Brüder Mannesmann M1130 stands out as a straightforward, no-frills voltage tester for automotive electrical work. Unlike digital multimeters that require battery power and interpretation, this test lamp gives an immediate visual indication of voltage presence, making it ideal for quick checks on fuses, wiring, and batteries.

Highlights

• Tests 6-24V DC circuits, covering most passenger cars and light trucks.
• Bright incandescent lamp lights up when voltage is present.
• Coiled cable extends to approximately 3.5 m for reaching distant points.
• Transparent handle lets you see the internal lamp and wiring.
• Alligator clip for secure grounding and sharp probe for piercing insulation.

In daily use

Connect the alligator clip to a clean ground point, then touch the probe to the circuit you want to test. If the lamp glows, voltage is present. The transparent handle provides a clear view of the lamp, and the coiled cable keeps the lead manageable while still allowing extended reach. This tester requires no batteries—it draws power directly from the circuit under test.
