To achieve a smooth, glossy finish, the rear light should be printed onto a build plate coated with polyimide film. Alternatively, you can also print the rear light onto a effect plate, e.g. with a carbon fibre pattern.

The two LED modules are simply slid into the opening, where they sit so securely that they cannot fall out or shift. As the rear light does not have a reflector, a separate reflector must be fitted.
