By headlight, do you mean the blue main beam light?

[scaffy]

yes, m8, engine manigment,abs,battery ,main beam,airbag, sometimes the battery goes flat aswell even tho its only about 4 months old

Sounds like an iffy earth connection to me. You will find a load of them under the battery tray ...........

As Rob says above, or could possibly be voltage regulator in the alternator

[I_want_an_Omega]

If you have a voltmeter (preferably digital), measure the battery voltage as you adjust the throttle setting. You can opearate it under the bonnet manually on non-facelift cars. See if there is a voltage that causes the problem to occur/resolve.

The voltage shouldn't drop too far below 13V, if its down at the 11 V or less level then you have a problem with either the battery or alternator - IMHO.

Everything should be steady at upwards of 13 Volts - although it will drop a bit when you crank whilst starting.

Try turning the headlights/heated rear window on, should drop a little, but not too far.
