is there a way that i would be able to modify a file so the lights work with my current vehicles?

Hi, I have tried to install these vehicles onto my fivem server but some of the vehicles lights aren't working, I have installed the carvariations, vehicle.meta the carcols, do you think that one of these files will be clashing with another in a different resource, its the boxvilles with lightbars, lcpd 1-4, lcpdmerit and lcpd uranus and fdlc that aren't working, if youre able to assist me that would be much appreciated, love the vehicles

Is there a template out for this vehicle for me to do my own liveries?
