Yes, in the discusion you had said you have sent them in for repair before (Service Department) However, all lights should be serviced on a regular basis...depending on use anywhere from once every other month to once every other week.... covers removed, debris blown out with air from the base and head, optics cleaned with a vinegar water mix (1 part vinegar to 9 parts distilled water) covers wiped down and cleaned. Then visually inspect all parts for normal wear and tear... This will help prolong the life of the internal parts to the lights as well as gives you a heads up if anything is starting to break down. Cleaning the optics will keep your lights looking bright and strong... as for the errors, please call service and we can assist you in troubleshooting down the problem with the error code 323.213.4593
