Review on HIKARI VisionPlus 9006/HB4 LED Bulbs: 15000LM, 30W XHP50.2 ⚡️ LED, 6000K Cool White, Waterproof - Upgrade Your Halogen Bulbs! by Paul Williams

I bought 3 of these to replace the factory bulbs for better nighttime visibility. One went into my 2015 Lexus RX and while it wasn't easy to install, it fits and works great! I then installed a second one in my 2011 Lexus ES - this setup also required some work but it fitted and worked as expected when enabled. However, on this model, daylight is the same as high beam, only with lower power, which caused the lamp to constantly flicker in this mode. There is another adapter that can be used to fix this but there isn't an easy install and there really isn't a place to put it so I removed them. As for my 2003 Corvette Anniversary Edition - again not an easy install but they got in - but they were too big to let the headlights close so got out. I ended up returning 2 of the 3 purchased. I checked both Revain and the manufacturer's reference materials to make sure they were the right bulbs for my vehicles, but it turned out they weren't. The return had to be done directly with the non-US manufacturer, which was a frustrating and lengthy process due to the language issue and time difference!
