one problem i just found no headlights all other lights work 

I notice from a previous post you've got an early TR6. What position is the column switch? Assuming it's the same as my Spitfire which is a similar age, top position is sidelights only, middle is high beam & bottom position is low beam.

First try the wires to the foot switch, blue -main feed should have 12v with headlights on. Could be a cable broken/unplugged or the switch.

If the foot switch is ok, there should be a join in the wires at the front valance; where the feed splits to both headlights. Break out the multimeter and see if you have 12v there. should be 3 sets of cables. Blue/White - Full Beam, Blue/Red - Dip, Black - Ground

If the ground is faulty or coroded then none of them will work.

yes flashes ok

Great as Richard says theres a power loss somewhere between the column switch and floor switch including the switches themselves. Earth looks ok as flash works👍

Success! But were there any other connections in the same area that might have suffered as well? How about some preemptive maintenance on those - theres nothing worse than forgetting all about it until you suddenly remember in a few years time just as you find a similar fault in the same area🤣
