Freelansir,
The essential point of the indicator light is given in the system's name "The Lorenz BLIND landing system". I.e. unlike your fs2004 picture the system was used when you cannot see anything out of the cockpit, it's dark or you are in cloud with a low base. Having reached your airfield via the homing beacon, when the lamp first lights you begin the glidepath descent to the runway. The second time it lights. and here's the good bit, if you cannot see the end of the runway it's time to get the wheels and flaps up and get the hell outa Dodge to go round and have another go!
I suggest that you download and read the release notes from the 4.10 patch available here:
http://www.mission4today.com/index.p...etails&id=3996
which is when these features were added to IL2. You will find the relevant info under New Navigational Objects. There are also some pdf's in the game's folder together with the game manual which contain lots of useful info.
See
http://www.usaaf.co.uk/forum/viewtopic.php?f=40&t=197 for explanation of the systems used by USAF in England during WW2. From there this image, is this in the game? click on images to enlarge.
Anyone whose wishes to learn more can download the Army Airforces' WW2 Air Navigation Manual from here:

You can download it in parts. The one most relevant here is:
Section 4: Supplementing Dead-Reckoning by Radio
The Radio Line of Position: The instruments and their use; Obtaining the uncorrected radio bearing; Converting uncorrected radio bearing to radio line of position; The radio fix and log; Other radio and communication equipment in the aircraft.
Additional Radio Aids: Radio range stations; Marker beacons.
and this page the most,
At about at the war's end the first completely automatic landing took place in England and is the forerunner of the system in use today. Some of you may not know but nearly all civil flights are landed today by the aircraft's onboard computer which may or may not make you sleep easier
