~$9. A superior quality product. thanks Jerry,on the instruction paper that came with it there are different diagrams,there are 5 different diagrams #1 says (1 ampload 4 units) #2 (2 amploads 2 units) #3 (4 amploads 1 unit) #4 (8 amploads 2 units) #5 (12 amploads 3 units) the units are the voltage reducers,the directions say determine the amp rating of the accessory it also says reducer is designed for 1.5 ohm resistance at 4 amp maximum load.exceeding this may damage the reducer and/or the accessory.I hope i only need 1 reducer because they are $12.00 a piece, how do i know what the amp rating of the accessory is?could someone tell me,its just an old 6 volt light that came off from old car,probably from the 1930s it has a bracket on light that someone told me it mounted to the bumper of the car.thanks for any help.
