*by G***D on Reviewed in the United States on February 8, 2016*

I used these to make a direct battery to light relay harness I could hook or un hook easily to run a larger (130/80 watt Hella H4) light bulb without burning up stock light switch(60/55 watt  H4 bulb). I cut and spliced so male plug fits into stock female plug from factory harness w/ light switch to relay and female plug from relay and 12 gage  battery wire into motorcycle male head light plug, makes it brighter with no voltage drop too. Can now be easily removed and put back to stock.
