car lights

[Matevsz]

Hi, i create x6 image and x6 button.

After pressing "lshift" shows 6 photos and now I would like to show one of the first button to the photo by pressing the arrow "arrow_u" and "arrow_d".

  
function carLights(value) 
local car = getPedOccupiedVehicle(localPlayer) 
if car and getVehicleController(car) == localPlayer then 
if value == true then 
guiSetVisible(photos, true) 
elseif value == false then 
guiSetVisible(photos, false) 
end 
end 
end 
bindKey("lshift", "both", function(key,state) 
if state == "down" then 
carLights(true) 
elseif state == "up" then 
carLights(false) 
end 
end) 
  
addEventHandler("onClientGUIClick", photos, function() 
local car = getPedOccupiedVehicle(localPlayer) 
if car then 
if getVehicleOverrideLights(car) ~= 2 then 
guiSetVisible(button1, true) 
guiSetVisible(lights, false) 
bindKey("arrow_u", "up", button1) 
bindKey("arrow_d", "down", button1) 
else 
guiSetVisible(button1, false) 
guiSetVisible(lights, true) 
unbindKey("arrow_u", "up", button1) 
unbindKey("arrow_d", "down", button1) 
end 
end 
end) 
  

what we could be wrong?
