'02 Mondeo lights playing silly beggers.

Symptom 1:The brakelights come on with the headlights (side, dipped & full
beam)

Symptom 2: When the headlights are off the sidelights (& brakelights) come on
when the brake is used.

I thought at first I'd dislodged something when shifting furniture yesterday
but apparently not.

Where should I be looking?

TIA

Sometimes a stop/tail light bulb can fail internally causing a short between
the two circuits. This would match your symptoms. Remove the stop/tail
light bulbs one at a time and test to see if all then works normally.
(Apart from the one you remove, obviously!)

Let the group know the outcome.

I had this on a motorbike once, tracked it down to the tail/stop light.
The filaments were touching each other.

Duff dual-filament tail/brake bulb, or a crappy earth to one cluster.

Almost certainly a faulty bulb. The two filaments in the brake/tail lights
will have become fused in one of the clusters.

Thanks everyone,

The bulbs were mis-matched - they'd been working for the 6 months since i got
the car but I guess one became dislodged & the contacts shorted. Correct bulb
in now.
