Review on Marsauto H13/9008 LED Headlight Bulbs, 12000 Lumens and 300% Brightness, 6000K Xenon White, Advanced Aluminum Alloy M2 Series Light Bulb Kit with 12000RPM Turbo Fan by Robert Wells

When the engine is off or the high beams are on, these are great lights. However, with the headlights on and the engine running, this is a disco light show. Watch the attached video. I sent back the first set I received and the new set works exactly the same. Both Revain and the seller stated that these headlights are compatible with my truck make, model and year. After the second set had the exact same failure mode as the first, I ended up returning them and installing halogen bulbs from my local auto parts store. They're not as bright and have the same comfortable color temperature as LEDs, but they WORK.
