Bad earth on the light? although unlikely if side lights work.
Check the headlight switch? Check all the wires going to the headlight for any breakages using the multimeter.
Might sound simple but blown bulb or fuse?
Got to be one of the above?

take the head lights of for the test it does not need them on if the tester ask when do you drive it you tell him or her daytime only they can not
fail it only advise that the headlights were missing at time of the test

I hope that is not the right answer....
I would measure with a Multi-meter if ther e is any voltage at the headlight. First with they minus at ground (engine or batt) .
If so, measure between ground and + at bulb.
If both not, then go towards the light-switch and steering column.
- Did you check the fuse?
- Did you check the bulb (12V?, both death?)
- Is there a relay for the head-lamps?
(Some circuits have)

i think you would get a "day light mot" if you did this better to fix if you can

What is not right about the answer if he does not get them working in time then that is the option............. legal option

no such thing as a day light mot if you are a mot tester then read the manual and the advisory options
if not a tester then do not coment on what you do not know

I get daytime MOT's every year for my motocrosser, been to many different MOT stations and all have given them out, no idea if its the same for
cars?

I think this has strayed somewhat off-point, the OP wants to fix his headlamps, not find a legal loophole!
However, DRC is right: there is no such thing as a 'daylight MOT' despite the popular misconception, it's just that if lights
aren't fitted, they aren't tested.
My understanding is that no lamps except stop and indicators are allowed to be fitted if you go down this line; prepared to be corrected though.

No main or dip headlights suggests to me that you're not getting any power beyond the headlight relay. Should be easy to check with a multimeter
if you're getting power to there. You should have a pretty heavy duty blue wire into the relay, and a blue / red and blue / white coming out
(assuming the general standardised wiring loom).
Start at the relay and if no power there, try the input of your headlight switch. My money would be on a broken switch.

Thanks for all the replys guys,taking the lights off is an interesting option but I think as a last resort.Fuse is ok cos side lights work ,bulbs
appear ok,will have to get hand in pocket and buy multimetre,thanks again for all the quick replys its reassuring to know you have this forum for
advice.Cheers Keith

I'm pretty sure that's what DRC was suggesting before he was (incorrectly) shot down...
My suggestion isn't the best one either - but you could just put in a new mini loom to get it throught he test...

You can always do a few simple checks with a length of wire (carefully).
1st step i'd try is take a live feed direct off the battery and with the headlight relay removed, touch the terminals in the holder with the
blue / white and then blue / red. If nothing then you know its the lights / no earth. If you get lights then you know its the power feed to the
relay.
Check the relay by removing it and bridging across the holder terminals (usually solid blue wire) to the outputs (blue / white for dip, blue / red for
main) with the headlight switch set to on. You can then work back through the supply to the relay - bridging across the input / output of the
headlight switch etc

WD40 on the switch gear, mine do strange things if it's been out in the rain and then dried out, don't forget the switch gear was designed
for a tin top not an open sportscar
