Like all other modifications, your custom headlights require care after being fitted to ensure that you get the most from your new purchase.

It's a similar situation to:

• When getting PPF applied to your vehicle - letting the PPF set, and ensuring that your car isn't aggressively washed on the PPF edges
• When getting your car painted - letting the paint cure & offgas, and not use any coarse polishing
• When fitting splitters or lips - avoiding kerbs/potholes or anything similar that would cause damage

As your new headlights are a custom/bespoke item, they also require you to take care of them to get the most out of them, as well as avoiding common minor issues. This is not an exhaustive list, but it'll give a good indication of what's required:

• Not pressure washing the headlight seals at close range to remove or disturb the replacement sealant when washing your car
• Not applying acidic products, or anything that will interfere with the sealant on the headlight when washing your car
• Not touching/removing/disturbing the sealant on the headlight
• Not removing any warranty stickers to ensure that your warranty is not voided
• When removing/replacing bulbs, ensuring that the bulb/gasket/bulb holder/cap is seated back on correctly to not allow any water ingress into the headlight
