Yeah, the gear lights in AH are kinda weird.
Being that pilots are usually guys that couldn't make the cut to be mechanics (understanding every component on a aircraft other than the auto pilot switch tends to be more difficult), the designers made aircraft very easy to fly and put in idiot proof logic. It's more commonly called a "lights out" or "dark cockpit" design. Another words, if no lights are on, everything is good, (or the pilot left the battery switch off) and when a problem pops up, a "BLAM, LOOK HERE GUYS" red light comes on.
If the gear lights are all GREEN, that should mean, "hey, we put the gear handle to down and they are all down and locked." Time to take off auto pilot and fly for next 3 minutes, wheeeee!
If they are RED, it means, "hey, we put the gear handle down or up and the gear aren't where they should be. SOMETHING IS WRONG.
You'll get this when the gear is intransit till they lock in the 3 GREEN down position, or into the wheel wells, at which time the lights should extinguish.
Sooo, a gear light sequence should go like this.
TAke Off-
3 Greens taxi for take-off. Upon lift of, move gear into retract. Lights turn RED intransit, and extinguish when locked into wheel well.
Landing-
Lights out. Move gear lever down, should show 3 RED intransit. When they lock down, it should show 3 GREEN meaning its all safe to bounce onto runway, ground loop and crash in front of the refuel shack ending a 7 kill streak.
