Absolutely no problem plugging it, very easy to read and see which lights are on and working, bright enough to see in the day, and very cheap great value for the money, i like it and will use again !

I was trying to diagnose whether my trailer light issue was with my trailer wiring or with my vehicle wiring. This allowed me to rule out my vehicle as the culprit. It does feel cheap and I am wondering about durability. It functions, but would probably not survive a drop.

This is a handy tool to have in the event you discover that you’ve lost your taillights. Just keep in in the glovebox of your trailer towing vehicle and you’ll have it if you suddenly need it; wherever you go.

The only way to use this is with a set of jumper wires…..in other words it’s pretty useless. Waste of time and money. It’s just not the right size.
