Lit Objects

This is a stylesheet for use alongside the builtin "Potlatch 2" style. The lit areas are deliberately very wide to allow space for other casing-based styles to be used at the same time; the analogy is that light spills out into surrounding areas. This stylesheet highlights lit nodes and ways, and also handles objects which are only lit some of the time.
