I don't know the amperage translation.
Charging system? We don't need no stinking charging system!
They are an easy electrical hookup.
They come with a lighted rocker switch, but I wanted some originality.
I cut off the original connection and used the double plug wire that it comes with.
I spliced the old and new together and heat shrank the connection.
They have individual ground wires. I put both of them to the frame with
a small bolt and nut.
For some reason they come with "wood" screws for mounting.
I did not even use the mounting bracket per say. I epoxied the lights
themselves into the plexi after carefully measuring and cutting out the
openings with a coping saw. Before hand I painted the back of the plexi
with flat black and it does give it some depth. I did plan on giving it
some silver pin stripes, but after it broke, I will wait until I make another.
Best part is made in the USA!

About $16
I even saw a driving light about the size and shape of the typical
wheel horse light cover opening. But you could only fit one light.
You could call it a cyclops??
