Hi,
switch (typeOf _vehicle) do
{
case "C_Offroad_01_F":
{
_lightleft lightAttachObject [_vehicle, [-0.37, 0.0, 0.56]];
};
You change your case, in this instance, "C_Offroad_01_F", it's your vehicle's class name. The lights position will vary but can be edited by changing the values. In this case, you would be changing [-0.37, 0.0, 0.56].
