Need some help on glowmapping

i'm trying to add a glowmap function to a mod i'm making (just to be able to see at night) and for some reason, when i try using this:

Spoiler: whats in my .jbeam file

{
"xs": {
"information":{
"authors":"frks3864",
"name": {
"txt":"ui.vehicleconfig.information.name.BRAND BRAND",
"ctx":{
"brand1":"ui.vehicleconfig.brand.(car name)",
"brand2":"ui.vehicleconfig.brand.(model name)"
}
}
},
"slotType" : "main",
"slots2": [
["name", "allowTypes", "denyTypes", "default", "description"],
["bx_body", ["bx_body"], [], "bx_body_hatch", "Body", {"coreSlot":true}],
["paint_design", ["paint_design"], [], "", "Paint Design"],
["licenseplate_design_2_1", ["licenseplate_design_2_1"], [], "", "License Plate Design"],
["bx_mod", ["bx_mod"], [], "", "Additional Modification"]
],

"scaledragCoef":0.84
"variables": [
["name", "type", "unit", "category", "default", "min", "max", "title", "description"],
["$brakestrength", "range", "", "Brakes", 1, 0.2, 1.0, "Brake Force Multiplier", "Scales the overall brake torque for this setup", {"minDis":20, "maxDis":100}],
["$ffbstrength", "range", "", "Chassis", 1, 0.5, 1.5, "Setup-Specific Force Feedback Multiplier", "Scales the force feedback strength for THIS SETUP ONLY", {"minDis":50, "maxDis":150}],
["$headlightPitchComp", "range", "degree", "Headlights", 0, -3, 3, "Setup Specific Headlight Pitch Compensation", "Adjusts the headlight pitch for this setup", {"minDis":-3, "maxDis":3}]
],
"glowMap":{
"xs_lights":{"simpleFunction":{"lowbeam":0.49,"highbeam":1}, "off":"saikoulights","on":"saikoulightsON_on","on_intense":"saikoulightsON_on_intense"}, <--this is what's causing the mod to break
}
},
}

i don't know if i forgot something or if I'm just doing the glowMap naming part wrong, but I hope that I'll somehow be able to fix this sometime...

 

so, i managed to get the game to not crash by editing the code, but now i'm stuck at trying to get the glowMaps to appear. i have another material for the lights when they're on (obvs named saikoulights_on), but for some reason it doesn't want to appear in my materials tab whenever i use the eyedropper onto the car (it appears when i search it and even says it's located in the materials.json where all my other materials are), and the light material refuses to work whenever i turn on the lights. Any tips?
