In the reviews... I am assuming that the complaints are probably because they have installed them incorrectly.
These can apparently be adjusted once installed.
I know that with the regular bulbs, you can actually get them installed at almost any incorrect angle. If the high and low beam sides are not on the correct up side or down, and if they are not aligned flat with the up or down, (horizontal axis), you can get problems like not enough light. And or high and low both putting out inadequate light, and showing almost no difference when you switch between high and low.
So as I said, I am going to assume these people just rushed out there and shoved the bulb in whatever way was fastest and most convenient for them, paying no attention whatever to the details. Got them in wrong. And now it's the bulb's fault...
But there are also a lot of complaints that the bulbs don't last long. Some only an hour or two. Some maybe a week or two.
Please let us know of any problems you might have with these.
You might also want to keep your old bulbs in the glove box, in case these decide to burn out on you while you are driving at night.
