modern-fringes is meant to replace the default fringes with ones that are more visually pleasing. They are very simple to use, just enable the modern-fringes-mode minor mode. You are able to use customize to make the mode permanent, as well as change other aspects. It is a global minor mode and will affect all buffers.

It is suggested to use the following function in your init file to use modern-fringes at intended. It matches the truncation arrow foreground color to the current main background color of your theme, making them appear transparent and less visually cluttering.

(modern-fringes-invert-arrows)

Depending on your theme, the function may make them look unappealing. In that case, you can edit the bitmap faces as you wish in your config.

modern-fringes assumes the fringe width is 8 pixels wide, and the bitmaps will likely look strange if the width is any different.
