94 lhs stop lights

Hi...

Wonder if anyone who has a 94 lhs/ny'er handy might do
me a favor and take a look at the brake lights with the
4 ways flashing? Or perhaps a turn signal?

Reason for wondering is that with mine only the bottom
segment of the two bulb system illuminates with brake/
turn/4 way's operating - and both the upper and lower
segments have dual filament bulbs and wiring. Both come
on with parking lights.

Can't figure why Chrysler would have installed wiring,
sockets, and bulbs for both if they were only going to
use one?

Thanks, and take care.
