They actually do work, but they're very faint. This has been brought up before, and I asked Jim about this and if he coded something in there that's causing this. What we found, and what he coded, was that in the actual Saab documentation, the engine annunciators are very difficult, if not impossible to see during daylight hours with the sun shining directly on them. To the point that sometimes the pilots need to cover them with their hands to give them some shade to see if they are working. I'll see if I can find the page in the documents this is mentioned and post back. For the next update, we might bump up the brightness a little, but we'll have to get feedback from a couple of pilots who have generously given us their time and some very valuable feedback, on the brightness.
