these are nice, but they seem to be single sided only, also i find you pay a lot more for the name brand for the same thing (made in china)
I find that products designed by a company like Philips and manufactured in China under Philips' supervision can be higher quality than products designed in China to be as inexpensive as possible and that are either sold to individuals on sites like Alibaba or to Western companies that relabel them with their own brand.
Five years ago, I installed Philips LED daytime running lights (DRL's) that were more expensive than DRL's sold on Alibaba or obviously relabeled by a Western company. These DRL's are on whenever I drive and continue to work without their LED's failing as seems to happen frequently with lower quality LED lights. Maybe I've just been lucky, or maybe paying a bit more for Philips DRL's was a smart move.
However, the Philips headlight bulbs referenced are H4 bulbs with both high and low beam LED's in a single bulb whereas the i3's high beam headlights need only high beam LED's. So one is paying for probably twice as many LED's as required and may be getting a bulb that doesn't work as well with a reflector and lens designed for a bulb with only a high beam light source.
While some of the Philips LED headlight bulbs are described as being optimized for reflectors and lenses designed for tungsten filament bulbs, it's just not possible for a LED bulb to emit its light from as tiny a volume as a tungsten filament bulb, so the light pattern produced by retrofitted LED bulbs will almost certainly be inferior to that produced by a tungsten filament bulb. The LED light color will be hotter (i.e., whiter) and the LED light intensity might be greater, but the light might not be projected where it should be. In many countries, LED retrofits are not legal because of this.
