Easy to use. A large screwdriver type
The perfect tool for the job. If you need to test if there’s current going through a item then use this tool. It’s a bit bigger than I expected nay it’s a lot bigger than expected. But it does the job and because of its size it’s very easy to use.

The voltage rating of the light needs to be checked before use as it blows if not rated properly.
It is a very handy tool to have when working on any vehicle, as it loads the circuit there by checking connections, but the wattage and voltage of the led (bulb) must be correct, otherwise like mine it will blow if not rated properly.
