I did this upgrade aswell but my bike now has two H4 bulbs, i simply cut a hole big enough for the H4 bulbs base on the side the H1 was on made a new clip to hold it in place fixed it on with a screw also sealed it with some hot glue from a glue gun just as safety works fine ill post a pic tomorrow.
