Should work ok
By : TJ
I purchased the Bully light; then purchased online a 12V waterproof 5-Pin Relay SPDT 30/40A with Metal Bracket ($2.89), a 12VDC 5-Pin Socket ($1.99), and an inline fuse for the reverse light wire to relay. I'm no auto expert, but I rather run the 5.83A thru my factory trailer package 12V wire than my reverse light wire. Item works great all wired up with the relay.
Light works great; but when backing my boat trailer, light doesn't get around bass boat very well, only to the sides a little since boat is blocking most of the light. If lights were farther apart would be better for me. Now backing an empty boat trailer down the ramp is another story, works great then.
