I noticed something kinda odd (maybe) on Superblack ('92 5.3). Seems whenever I close a door the interior lights only stay on for a few seconds before shutting off. On Superblue ('94 4.0), by contrast, they stay on something much longer, like 15-30 secs. Is that the norm, or is Superblack’s lighting timing module a bit blinky (no pun intended)? 
My 93s stay on for about 10sec give or take
Mine used to stay on for about 10 seconds, then a slow fade to off. After switching to LED bulbs the time is shorter and there is no fade.
