Review on Everbright Interior Reading Ceiling 4Festoon by Brant Skogen

I've had them for almost a year now. Put them in my truck. I've only driven the truck about 2,000 miles since I installed them. At first they looked great. Nice and bright. About 5000k+ per color. My main light now flickers and puts out about 10% of the usual light. Also, I only received three in a pack of four. At first I didn't care, but now I understand that you need at least one backup. I would look elsewhere for better quality or durability.
