I’m excited to introduce you to a powerful tool that can elevate your trailer-testing experience. This device is energized by a Milwaukee 18v or DeWalt 20v drill battery, connected to an 18/20-volt converter that efficiently delivers a 12-volt output with an inline fuse for safety. With six independent switches, you have the power to control:

- 7 Blade RV Plug - 7 Round for Semi Trailers - 4/5 Flat trailer connections It also includes a versatile 7-pin trailer plug adapter for testing both 4—and 5-pin trailers, simplifying your tasks. When you activate the switches, the turn signals flash, providing immediate feedback as you test: - Left Turn / Brake Light - Right Turn / Brake Light - Running Lights - Reverse Lights - Stop Lamps - Trailer Brakes - Side Markers / Clearance Lights - 12-Volt Accessory Keep in mind that the battery isn’t included, but this should not hold you back. I’ve rigorously tested this tool on my own 4/5 Flat trailer and 7-way trailer/semi-trailer to ensure that it performs beautifully, paving the way for your success. If you have any questions or need support, please reach out. Together, we can make your experience smoother and more rewarding!

Please let me know which adapter you will need thank you
