The Optimum Series 4 single and dual beam LED headlight bulbs and drivers are backed by a Lifetime Warranty.
On the very rare occasion one of our LED headlight bulbs stop working, there is a small amount of troubleshooting you will need to do to find out what needs to be replaced. It probably won’t be the bulb. It may instead be a bad driver, loose/broken plug on the vehicles wiring harness, or a bad fuse.
