after taking out the headlights, remove the bulbs and retaining clips and use a heat gun to loosen the seal and separate the lens from he housing.then remove the three screws holding the amber in. i didnt even bother resealing them, they only retain moisture if there is a small break in the seal. if the light isnt sealed airtight all mositure will evaporate form the light. but i painted the housings blue, so i wanted some ventilation for the heat.
