Are fogged up headlamps an MoT failure?

My 2017 Suzuki Baleno headlamps are fogged up around the outsides but not in the middle - it appears to be between two layers of double glazed plastic? Is this an MoT failure?

Is there a fix for this because replacement headlamp units are horrendously expensive?

The MoT guidance says that water or condensation in your headlights will be a failure if it affects the beam pattern, so as the moisture is around the outside of your headlights it may still pass.

This has occurred because the seals around the headlight have failed and allowed moisture to enter, which is then evaporated when the heat of the bulbs is present. The best solution would be to remove the headlights and dry them thoroughly indoors before resealing them. You may be able to purchase a set of rubber seals separately, but failing that you can use a waterproof sealant from an automotive accessory or DIY store.

Punchy and efficient petrol engines especially the 1.0-litre Boosterjet, excellent value for money – even the top trim is well priced, more spacious and practical than the Suzuki Swift.
