How to make headlight effects on a sprite? (Increasing emission of sprite material)

Hello everyone,

I created my project by selecting the 2D feature. I have a car sprite in the game and I want to increase the emission of the car's headlights, so that should give the headlight effect as if the lights are turn on. I know how to do it theoretically, but I don't know how I can make it on Unity.

I have a car sprite, which is going to be albedo, and a mask for the headlights. (In the mask, the headlights are completely white and the rest is completely black). I need to multiply that mask by a number and give the result to the emission output. The car sprite itself will be the albedo output.

Is it possible to create a material for sprites? If so, how can I do this?
