Monkey - most cars get condensation in the headlights as the other chaps are kindly telling you! The weather is damp, miserable and cold. Your engine is toasty and warm. As long as it's just a centimetre or so at the bottom of the light it's not so bad.
Don't tell me, you're going to take it into the dealer for steamy windows next?
