Here is a good example of what I’m looking for: http://media.moddb.com/images/articles/1/143/142220/auto/sineicos-night.gif
I uploaded a screenshot of what I have currently (just a light, heh).
A simple point in the right direction would be great 
EDIT: On second thoughts, these light effects are probably baked into the scene, aren’t they?
Yeah, I don’t have any real knowledge of what they did, but it looked to me like it was drawn directly on the sprites.

Could be using normal maps on sprites, checkout Sprite Lamp (and other similar tools)
Take a look at this guys: https://www.assetstore.unity3d.com/en/#!/content/21770
Thanks mgear, I’ll have a look now.
