Thinking about getting a test light with adjustable load
Has anyone tried using those modern test lights that let you apply adjustable load to the circuit? We’re still using old-school incandescent testers, but they’re not always reliable on newer cars with sensitive electronics. I’m considering switching to a load-type test light for more accurate wiring checks. Curious if it actually makes a noticeable difference in diagnostics.

Load-type test lights are actually more useful than they look, especially when you’re diagnosing modern cars where a regular bulb tester won’t show weak grounds or voltage drops under load. A proper load tester lets you apply controlled resistance to the circuit and see how it behaves in real conditions, not just whether power is “present.” It helps catch borderline connections, corroded wires, and intermittent faults much faster. For anyone thinking about adding one to their toolkit, ECUTools offers several load-type test lights that are simple to use, built tough, and accurate enough for daily electrical work. They come with clear specs and reliable construction, making them a good option for workshop diagnostics: https://ecutools.eu/
