I always have removed the underhood lightbulb on my vehicles since I had a battery go dead on my '79 F150. I had parked on a hill and the mercury switch for the underhood light was left "on".
Lo and behold, I discovered it was no longer necessary on our MM's. It seems we can leave a door, trunk, or hood open, and the light circuit turns "off" (after a while) to save the battery.
I'm sure there are other owners that didn't know this, as I believe our owners manuals don't really mention it.
Yep, every single 1995+ panther features 'battery saver', integral to the LCM.
It will turn off a lighting circuit after a pre-set amount of time elapses.
It will also diasble a circuit if it is determined to be erratic (ie a bad switch)
The head and courtesy lamps will automatically shut off after 10 mins.
The demand lighting (ie reading/map lights/under-hood lamp) is shut off after 30mins.
These times are after the last time power was activated or interrupted to any of the LCM demand, courtesy, or headlamp outputs.
These days cars use a small ball bearing tilt switch in place of the very hazardous mercury.
BTW, I saw a few ask in here. For those looking to add an underhood lamp, don't be discouraged if the wiring is not present. I added an under hood lamp to my car and it was extremely easy;
Grab yourself an underhood lamp (typically includes bulb, otherwise grab a wedge base clear bulb) and the Motorcraft pigtail ( E8EZ14489-DA for most Ford underhood lamps). Solder/heatshrink/wrap (or crimp connector if you can't solder) the new pigtail to a ~5ft length of ground wire, and ~ 10ft of positive lead wire. Run the wiring, in nice neat wire loom (make it look factory, spend the time to wrap the loom with electrical tape for OEM appearence) down the hood, and use one of those plastic push pins to secure the end of the loom in one of the holes in the hood. Then route it down towards the PCM harness area, make sure to provide harness slackl for hood opening/close. There is a ground nearby on the fender, so just run the ground lead to there. Then route your positive wire lead through one of the fire wall grommets and into the dash. From there, the easest place I found to wire it to and have access for the splice is to the glovebox door switch and lamp.
This switch/lamp is part of the LCM's demand lighting output feed, and thus is protected by the battery saver. Tap the positive lead (it is LG/OG on MMs) I prefer to cut, solder, heatshrink then wrap. A 't-tap' connector will work if you're lazy.
The process is the same for you cars as it was mine, You will now have a fully functional, fused, and battery saver covered under hood lamp
It would be a good idea to put a little di-electirc grease on the bulb's wedge abse and the lamp's connector to prevent moisture intrusion and corrosion.
Also, FYI, if the underhood lamp wiring is indeed present, it wil be around the brake booster area. A two pin connector, one LG/OG wire, one BK. Otherwise you need to tap the large c268 underhood harness connector (pita) if you don't want to run the wiring inside
