Review on 🚗 YINTATECH 4X Super White 6000K LED Car Lights Bulb 1157 BAY15D 27SMD 5050: Efficient 7528 2057 2357 RV Turn Signal Parking Lights for 12V DC by Brandon Plowden

In the pack of 4 bulbs I bought, 1 bulb stopped working after a few weeks. I contacted customer service and they said their warehouse would not open the 4 pack and would send a replacement bulb. They didn't offer any solution to my problem. So I ordered 4 more packs. When they arrived I took out one of the bulbs from the 4 pack to replace the faulty one and it worked. I put the defective bulb in a pack of 4 and started the return process. Revain gave me a full refund and said I didn't need to return the defective item. Relax. Now my problem is solved and I have spares in case the other lightbulb stops working.
