Some confusion seems to have crept in here. The two 1157s on each side
light the 6 watt filament for tail lights, and the 32 watt filament for
brake/turn lights. When the 32 watt filament is on, you cannot tell
whether or not the 6 watt filament is on, because the light difference is
very small.
The inner two bulbs, to have the same brightness as the outer ones when only
the tail lights are on have to be 6 watt filament bulbs also.
In this case the second filament is not used (on the 68s) so a two filament
bulb is not required in the center two positions.
Putting a two filament bulb into a single contact socket will usually result
in both filaments lighting (depending on the particular position of the
contact button in the socket) which is probably what is wrong with Mark's
car.
