Nice! Don't do as I do, Do as I say!
I'm afraid that you caught me there, and I deserved it!
Apparently, the tri-bar is acceptable, but the mount is not because of the lack of adjustment. But I have to say that I feel a whole lot safer with this lighting. I can see deer a lot sooner, can pick out the potholes a lot easier, and in the past two years I have never had motorist's flick their high beams on and off at me.
By the way, when you hook these up, test carefully to make sure that you have the right wires on the right terminals. You can get some really poor results if you have them mixed up. Once you are happy, make a note of which colour goes where for future reference. I found that the lamp would work with any of the 6 possible combinations, but there was a huge difference between right and wrong.
