This is looking good but may be somewhat complicated. I made a bucket level, several years ago, using a freebie Harbor Freight LED light. Fairly simple. When the light turns on the bucket is level. Works at any height. Has visual n light reference. Is easily adjustable for other angles besides level. I haven't tried that trick yet. The down side: by design the light flicks on n off with tractor movement, although not a significant problem. In the sunlight the light may be more difficult to see. Forgetting to turn it on or off. An upgrade was to run the wire up loader arm where switch is easily reached. And convert to the new 27 LED light. I may get to it some day. Right now I have to check the batteries n see if it still works.
