Review on AUTOGINE 4 X Super Bright 9-30V 3157 3156 3057 3056 4157 LED Bulbs 3014 54-EX Chipsets With Projector For Tail Lights Brake Lights, Brilliant Red by Joel Wright

These are very bright but they need a resistor for most cars. I have installed these on our Ford Focus and Hyundai Sonata (different model, same brand), both needed relays so they wouldn't hyper flash. On the Ford, the front turn signals stayed on the entire time and would not flash while the back worked perfectly. The resistors were $8 bucks here on revain and fixed the problem with them not working. Just know that these resistors get very hot and I mean VERY hot. They must be mounted against metal and not plastic. I took some heat sinks off an old computer and glued them to the resistors and they run pretty cool with the heatsink. Less heat means less breakdown of the metals so they will last much longer the cooler they are. The brightness is great, even with rear tinted lenses these can be seen clearly even during the daytime. I purchased a backup set just in case but so far they have worked fine. I purchased these on July 17th, 2020, and installed them on the 20th and they are still going strong. FYI these fit our 2003 Ford Focus ZX5 perfectly.
