Lighting up Linerenderers

So I’m using a line renderer to make a laser pointer type thing. The problem I’m facing though is that at night time the “material” is not lit up like it should be. Is there a way to add a light JUST for the laser to make it Illuminate perfectly? Or a way to make it not accept light changes and keep the color a solid bright red?
I’m using javascript and the game is a TDS.


There’s even the source code for a tiny solid red shader here:
