1-script not work

2-i want work script in start not i entred cars

local shaders = {} 
  
addEventHandler("onClientElementStreamIn",root, 
    function () 
        if getElementType(source) == "vehicle" then 
            loadVehicleLights(source) 
        end 
    end 
) 
addEventHandler("onClientVehicleEnter",root, 
    function () 
        loadVehicleLights(source) 
    end 
)         
  
function loadVehicleLights (vehicle) 
    local controller = getVehicleController(vehicle) 
    if not controller then return end 
    local image = getElementData(controller,"vehiclelight") 
    if not image then return end 
    if not shaders[image] then 
        local texture = dxCreateTexture("images/vehiclepoldecals128.jpg","dxt5") 
        local shader = dxCreateShader("lights.fx") 
        dxSetShaderValue(shader,"gTexture",texture) 
        shaders[image] = shader 
    end 
    engineApplyShaderToWorldTexture(shaders[image],"vehiclepoldecals128",vehicle) 
end 
  
function unloadVehicleLights (vehicle) 
    local controller = getVehicleController(vehicle) 
    if not controller then return end 
    local image = getElementData(controller,"vehiclelight") 
    if not image then return end 
    engineRemoveShaderFromWorldTexture(shaders[image],"vehiclepoldecals128",vehicle) 
end 

and thx all

Try this:

addEventHandler ( "onClientResourceStart", resourceRoot, 
    function ( ) 
        local texture = dxCreateTexture ( "images/vehiclepoldecals128.jpg", "dxt5" ) 
        local shader = dxCreateShader ( "lights.fx" ) 
        dxSetShaderValue ( shader, "gTexture", texture ) 
        engineApplyShaderToWorldTexture ( shader, "vehiclepoldecals128" ) 
    end 
)
