backup & reverse lights dead

[ADRNLN]

The car: my '87 coupe.

The problem: a few weeks back, reverse/backup lights only came on when handbrake was pulled UP. When brake lever was released (down), the backup lights would go out -- even though the car was engaged in reverse. NOW, the backup lights don't come on at all, and -- oddly -- neither do any of the brake lights -- neither the normal rears nor the rear windshield-mounted third brake light. Brake lights don't come on when I step on the brake pedal, either.

Fuses check out OK.

Could these two circuits be related somehow? Might there be a common connection or physical terminal somewhere to check? I highly doubt all the bulbs are simultaneously blown; there must be another related cause... Car has no other "symptoms" or other electrical problems.

Any thoughts?

Thanks,

Check the rear fuse relay in engine compartment. Lots of areas where they might have loosened and/or disconnected.
