A way to create authentic light (emitting) strips

Is there a way to create authentic looking light strips in source without using multiple point- or spotlights?

make a mapname.rad file (it’s just a text file)


texturepath/texturename		Red Green Blue Brightness


lights/white002			189 233 247 425

Thank you, where should I put it in?

//EDIT: I put it in the same location as the .vmf but it doesn’t work
