Just to be clear I run H4 LEDs in conventional 7" lamp units and not the specific LED lamp units.
It's a mixed bag, I've tried so many lamps and bulbs now and not kept a particular record.
Some do throw their light up to the left and I get dazzle from the very reflective signs.
Sometimes dip is worse than main as dip will always orientate towards the nearside and a bit of "up scatter" is designed in for the very purpose of illuminating signs. So when you start playing with bulbs or LEDs not designed for the particular lamp, you tend to get different and sometimes very strange results. I had one combo that dipped almost vertically to the left.
Most H4 LEDs have the dip beam permanently on and only the main switches in and out, so if it's the dip that is causing all the glare from the signage, you're a bit stuck.

I haven't found the holy grail yet, so all I can say is keep looking.
