        Since it's up for the moment, this one has always interested me.

        I'm well aware of the '92-'94 cars doing the low beams off with high beams, but I've encountered a few people with '95-'97 models who said their cars work like the '92-'94 models. On another forum someone thought I was crazy when I mentioned all four of my lights are on with the high beams, as their late Aero didn't do that. I've been curious if there is some weird differences in the '95-'96 LCMs versus '97.

          Since we're here...to be technical...the boxes turn the low beams off when the high beams are on.

          The low beam lamp contains two filaments, one low and one high. Therefore, the high beams are just high beams. It just so happens that Ford specced a dual filament lamp and that's why we get four that light up.

          The exception is flash to pass, where the highs come on in addition to the lows.

          So electrically speaking, the lows are not on when the highs are on. The circuit is therefore probably more similar to the pre-LCM Aeros than one would readily assume. What I don't know is how many filaments an early area "normal headlight bulb" has.

            Regarding the Boxes, IIRC, the "high beam" filament on the low beam lamps are 35W, which is why they appear considerably dimmer than the high beam only lamps, as the normal low beam filament is 55W. I know the low beam lamps don't really help much when the high beam lamps are switched on normally.

            The Aeros used a 9006 bulb on the low beam and a 9005 bulb on the high beam, so just a single filament for each position.

              yeah... the actual circuitry between the boxes and early aeros is pretty much exactly the same except for the updated autolamp relay. Just the single filament lows on the aeros.
