Meet "Load it" The Testlight
I have had a number of requests for this and it is finally here.
Note that this is NOT the same as the test light Jay Quinlan and I designed a few years ago. That one is only available through the link (ebay.io/m/XJsnG6) Any other units by other sellers are copies.

LOAD-IT!™ The Test Light
Stop chasing ghost voltages. Portable, modular current-load testing right in your pocket.
Standard high-impedance test lights and digital multimeters are great for verifying static voltage—until you run into high-resistance faults, green rot, or loose terminal tension. A standard meter will show 12 volts across a single remaining strand of wire, leaving you chasing your tail.
As a companion to our flagship Load-It diagnostic line, Load-It! The Test Light gives you a streamlined, ultra-portable way to put real work on a circuit right at the probe tip. Depending on your selected bulb, it pulls 720mA to 840mA—nearly 1 full Amp of current—forcing high-resistance faults to reveal themselves instantly. If a circuit can't handle a load under real operating conditions, the Load-It! won't light up—period.
Maximum Lead Versatility: Dual 4mm Banana Jacks. Unlike standard test lights with fixed, hardwired leads, Load-It! The Test Light features standard 4mm female banana jacks on both ends. This fully modular design lets you configure the tool for whatever the job demands:
Because Load-It! The Test Light actively draws up to 840mA, you must know the circuit specifications before testing.

Maximum Lead Versatility: Dual 4mm Banana Jacks. Unlike standard test lights with fixed, hardwired leads, Load-It! The Test Light features standard 4mm female banana jacks on both ends. This fully modular design lets you configure the tool for whatever the job demands:
- Probe + Lead: Pop a probe tip on the front and a ground lead on the back for traditional handheld testing.
- Dual Leads: Plug standard banana-to-banana test leads into both ends to connect alligator clips, wire-piercing probes, or back-probe pins hands-free.
- In-Line Circuit Testing: Use it in-line between power and ground rails to test component feeds directly.
- Dynamic Current Draw: Pulls 720mA – 840mA (depending on bulb choice) to stress-test wiring, relays, switches, and ground connections.
- Dual 4mm Banana Jacks: Maximum flexibility—use with ground straps, leads, clips, or piercing probes.
- Included Lead: Every unit ships standard with a heavy-duty, flexible 4mm banana ground lead so you're ready to test right out of the box.
- Field Serviceable: Swap bulbs easily on the bench to adjust your target load or replace spent elements.
- Magnetic: All Test Lights ship with a removeable magnetic clip
- Power & Ground Feed Diagnostics: Instantly verify main ECU power feeds, body grounds, and fused power distribution rails under real load.
- Fuel Pump & Fan Circuits: Verify that relay contacts and wiring harnesses can deliver actual operating current before dropping a tank or condemning a module.
- Relay & Switch Contact Verification: Identify pitted, burnt, or high-resistance relay contacts that pass static voltage tests but drop out under load.
- Trailer & Lighting Harnesses: Quickly locate voltage drop issues on long, high-resistance wire runs.
Because Load-It! The Test Light actively draws up to 840mA, you must know the circuit specifications before testing.
- Do NOT use this tool to back-probe sensitive 5V reference circuits, low-current sensor signal lines, or direct ECU/PCM micro-driver outputs (such as direct 50mA logic gates).
- DO use this tool on 12V power feeds, fused power distribution circuits, relay control outputs, ground rails, solenoids, and high-side driver lines designed to carry current.
1. Select Your Target Load (Bulb Choice):
- 720mA Configuration
- 840mA Configuration
- Standard Rigid Probe Tip – Ideal for terminal pin testing, back-probing weather-pack seals, and standard connector checks.
- Power Probe "Penetrator" Tungsten Carbide Tip – Ultra-hard, razor-sharp tip designed to easily slice through tough wire insulation without slipping or bending.
