We are sorry you have problems with your vehicle. At no time did we offer to 'seal' a taillight. Your tail light assemblies have moisture in them because they are not in proper shape to pass inspection. 'Lenses must be intact, clean, unobstructed and free from cracks,' is how the registry describes this law. Replacement of the tail light assemblies with parts, labor and tax came to approximately $394 as clearly stated on your repair order. We wish you and your vehicle the very best and happy travels.
