Why a 4 Flat to 7 Round Adapter is Necessary

I couldn’t imagine the risks of being on the road without a fully functional lighting system, and this adapter gave me peace of mind knowing that I was compliant with road safety regulations.
Lastly, the convenience factor cannot be overstated. I appreciate that I can easily switch between different trailers without needing to rewire or purchase multiple connectors. The adapter
