I got this Delta teacup light last week
Need the mounting bracket . Not sure what it looks like , round or square because I don’t know how this one mounts .
I thought truss rods but not with one square hole and angle of mount puts the light pointing straight up or straight down .
Then I thought steering tube mount like a Raleigh lightweight with the square tab you slide the light over but can’t remember seeing an English bike with a Delta light or any other Delta light with an English type mount.
Anyone know how this light mounts ?
