I made these 10 XML gauges to emulate FSX's wingtip contrail effect. Each gauge will turn on a light type in the [LIGHTS] section of the aircraft.cfg when the aircraft is over 174Knots/200MPH/323KPH and G is +1.5 or -0.5. If you want/need to edit the values you can with notepad .etc. Gauges for every light type and contrail effect included.
