I bought a round headlight thinking that it would fit the same as stock. Boy I was wrong. The back of the headlight housing prevents the tach cables from fitting properly. It would require modifying the back of the headlight which I don't want to do, so I'm wondering if anyone would be interested in buying? Maybe not for a GS but as a part for another project bike. I will post pics soon, but it's brand new and never used.
I also have a stock GS500F headlight in great condition if anyone is willing to trade their GS500E stock headlight.
