nevermind, i found the answer in a russian forum, for whoever needs it, add this in your artifact.ltx file in gamedata>config>misc:
trail_light_color = 0.6,0.6,0.5
trail_light_range = 1.0
under the line: lights_enabled= true. in the section [af_medusa]
so it looks like this:
lights_enabled= true
trail_light_color = 0.6,0.6,0.5
trail_light_range = 1.0
