Libgdx 2D Lighting on Tiled Map

Hi,

Could anyone please explain a method to create 2D lighting on a Tiled map? I would like to be able to place a tile or object with set properties which define the light, then have the light be produced in game. The light should just increase the brightness, and change the colour tint of the surrounding area, within a set radius. How would you go about implementing the lighting effect? Would you somehow modify the graphics of the tile, or maybe draw a layer above it?

Any ideas will be greatly appreciated.

Thanks!
