I've been running their LED headlights for a little over three years. When I had an unexpected headlight failure, I recached out to their customer service to enquire about warranty coverage fearing I was outside of the service window. Without hesitation, they said they would ship me a replacement LED. If that is not service, I don't know what is! Thank you Cameron! I would not hesitate to recommend them and their products to anyone in the market. Thank you Diode Dynamics! You have earned a customer for life!
