We offer a 4-year warranty on all our lights for normal use and against manufacturing defect with a no quibble guarantee.
Due to year-on-year improvements and upgrades within the automotive industry, Weisertechnik can only issue a warranty on a product for the model and year it was originally sold for. For example, if you buy your lights for a 2022 bike and in two years’ time decide to move them on to a 2024 model, we cannot guarantee they will work. However, if you were to move them to a 2020 model they will work. In other words, Weiser LED lights are backwards comparable but not forwards compatible.
