Escort 1.8 headlight problem - roda

I have a Ford Escort 1.8 si built Sept 1995.
Until recently the headlights have been fine. Suddenly (after a car wash) the dipped headlight on both sides stopped working.I have checked fuses, relays and connector on both bulbs and can find nothing wrong.

Please can anyone help with this nagging problem.....

Could well be the old problem of fault in fuse/relay box.Dry solder joints on the printed circuit can cause failure of high current consumers;usually headlights &heater blower motor.Could be as simple as 2 dud bulbs??

The earlier Escorts (mk3) suffered "meltdown" in the dip/main beam stalk. A high resistance joint occured inside and melted the plastic, causing the dip beam to fail.

Not sure if same applies to later models or not.

Thank you all for the help. We have taken the fuse box out and have found some dry joints - just as you suspected!
Now it is a case of repairing these joints - or replacing the fuse box. I hope they arent too expensive!!
