Although you can't capture the true beauty of sunset light you can do a somewhat realistic effect in Lightroom. You need to scroll down on the sidebar until you reach split-toning. In there you should see sliders. You then set the highlights to a gold-ish colour (you can tweak this) change the balance to something in the region of 60-100. and the shadows to a grey-blue colour. Tweak to your liking. I also like to add a radial filter and move it to where the light source would be, invert it, and apply a slightly warm temperature and increase the exposureslightly. Thus making a somewhat nice glow around the light source.
