Ray, you have to add the gauge in the panel.cfg of the airplane and in the aircraft.cfg you have to add the effects as light effects (in the "lights" section of your aircraft.cfg).You could also use "Flusi-Fix" (please read my reply to Graham).The only difference is, you don't select "Ai-traffic" in the "Flusi-Fix" menue (select "Aircraft.cfg"):http://forums.avsim.net/user_files/183247.jpg

Hi Nils, Thanks again for your help,I'll give it a try. Cheers Ray.

Thanks again Nils - I'll give this a try.

Well I followed your instructions Nils but although it appeared to have said that the effect was installed to my AI aircraft when I checked around I couldn't see anything had changed in the aircraft.cfg files etc - Then I used the translate gadget which showed that I had to select the aircraft I wanted to install the effect and then (I hope) click the button below. That semms to have done the trick - and the effect appears very well in FSX.Thanks again.
