Taillight mount and fender for Delta rear bike rack

The Delta Cycle Megarack Ultra rear bike rack has a strange back end makes it hard to mount a tail light securely. There's a thin metal tab sticking down with a couple of holes in it, as well as two vertical mounting holes on the rack top plate (see the pictures in the link).

This mount accommodates the features of the bike rack, making use of the two screw holes at the top as well as a screw hole the tab (which sticks down through this mount). With this mount, you can attach almost any saddle-post taillight onto the back of the bike rack. It includes a mini-fender that serves as a flange to prevent the taillight from slipping off.

The fender also protects the tailllight from debris thrown by the rear tire, as well as protecting you. The top plate of the rack serves as a fender to protect you from splashing, and the taillight fender improves this function by extending the protection rearward.
