need a tow light adaptor for light towing, where to find part

Hi, I have a 2001 Range Rover 4.6 se and need to tow a small trailer my 4 wheeler. I read somewhere online that one can purchase a adaptor to get a straight 4 tow light working with the RR, but the link had expired. Anyone know where I can purchase this? site sponsors are welcome

I am located in middletown NY and travel to NYC frequently if that helps
