How?
With no cutoff shield for low beams it's not possible to tune the beam appropriately in a reflectorized housing. I know that PIAA states there is a "sharp cut line" but I'm not feeling it.
If you look at his first picture (bulb in the box) there's a shiny metal "nub" at the front-most LED chip (low beam). That's a small shield to block output to the bottom half of the headlight reflector, which is the high beam. Similar to a H4 halogen.
I've been running a different brand H4 LED headlight conversion on my dad's CRV, a copy the Philips H4 LED design X-treme Ultinon LED Car Lamp 12953BWX2 | Philips with some slight improvements. It has rotational adjustment so I could "tune" the cutoff and it did help. It was also cheaper than Philips or PIAA,been running them since December 2015 and no issues so far.
DISCLAIMER: I'm a proponent of HID projector retrofits, no need to start a discussion about how they're better, I already know that from personal experience and not just from things I read on the internet
