Car dolly

I have been using a tow dolly for almost 10 years and I never tow without rear magnetic lights on the back of the tow vehicle both day and night. Right after I bought it people were honking their horns at me when I made a turn because they had difficulty seeing my turn signals and brake lights ( I tow an SUV). I bought a set of tow lights that had red lens facing to the back and yellow lens facing towards the front which allowed me to see if the lights were working correctly. Only cost about $25.00 and never got honked at again. Felt safer since I could always see the blinkers working (or on occasion NOT working). Wiring was easy since I put the connector on the trailer tongue then ran the light wires to the back (I wrap the slack aroung the rear view mirror). I think I bought the lights at Walmart or Harbour Freight.
