Review on Upgrade Your Car Lighting With Phinlion'S Super Bright DE3175 LED Bulbs - 500 Lumens, 3030 6-SMD Festoon, Pack Of 4 by Brandon Daughenbaugh

Didn't last very long, less than 6 months, before the circuitry started to malfunction and the lights would randomly flicker and then go out. Happened to both the red and bright white packs I bought. If this was something that took a lot of effort to replace, it's not worth it but they are bright when they're actually working. Over the long run, they probably are cheaper than going to something of higher quality if your able to manage with a product that could stop working at anytime.Update: two more bulbs went bad at 8 months of use. Supposed to have 1yr warranty but I get no response back from customer service.
