there is no separate fuse for auto light - nothing else comes on - not the taillights just the head lamps - sometimes its 5 minutes after you get out of the car another time I thought I had it cured for 2 days but then it went on the blink again - its definitely not a short.

will give it a try but at this stage I feel like setting fire to the whole car - this means ripping the whole dash out of course

yes back to original problem

Well just when I thought I was out of the woods - its back to square one again - flat battery this evening even after fusebox replacement - any other ideas?? Lexus in NI say they have never heard of this problem and are not accepting liability.

Have already replaced fuse block and the problem has stopped. Mechanic does not think water got into the original one though. Anyway so far so good. At least I 'm back on the road.

Having tried all the other suggestions already it sounds like Chris Shipley has the answer - will try and get fuse box and let you know. This has been driving me crazy for days so thanks

Even if the light switch is in off position and the key out they still come on - think it is more likely to be the auto light sensor?

Battery is going flat all the time as the lights decide to turn themselves on - when car is locked, ignition key out etc. Car just out of warranty and has baffled all local mechanics - anyone any ideas
