All of our custom builds have a 6 month workmanship warranty. To avoid having the headlights sent in to us, we will first troubleshoot and resolve any issues remotely. If the headlights need to be sent in for warranty reasons, you will be responsible for shipping costs to us, while we will cover the return shipping.If the service was for a drive in/out package we will cover the labour costs within 6 months of the original service date. After 6 months of the original service date, charges will apply to remove the headlights for any diagnostic or warranty work.For warranty claims on components after 6 months of the headlights leaving us, there will be a labour charge to replace the component while the component itself may be covered depending on the manufacturers warranty. Customers are responsible for shipping costs both ways.The warranty is for the original purchaser only, and not transferrable.
