Brake lights working, but with headlights on no brake lights!.....well, brake-lights/rear-lights are on but no further illumination from the rear when braking!

Is this normal? has only single filament bulbs been stuck in? or ???

truck 30 miles away at mo so can't just stick head out door and investigate!

any thoughts?

Brake lights should be brighter than rear lights - if there's no difference in brightness then it could be single filament bulbs fitted (although these have offset pins to stop this happening) or the rear and brake light wiring could be shorted together. Has this recently happened or could this be the result of someone bodging?

Check the earthing on the rear light clusters. If the earth is poor you will get all kinds of funny symptoms.
