First time I saw the bulbs after opening the box I could tell they were high quality! They are very bright and well. I would definitely purchase them again!

Installed these in my 2011 BMW 328xi. Replaced the stock halogen lights. They are fantastic. Very bright and very even beam pattern. Considering them for my BMW X3.

Great. Much brighter. Very clear lighting.

Absolute fanboy of HR. I have their products in both trucks and both my motorcycles. Night and day difference and they have done the homework for you. Plug in your ride... takes all the guess work of idiot owners like myself out. Much appreciated. The only issue I have is that when I replaced my HIDÄôs in the bmw, the stock light housing was not designed for the deeper heat sink of the LED. but thatÄôs not a HR or product issue ... often is the case for the cover needing to be updated/upgraded. Still searching for the cover, but it rarely rains here and the bike never sees water so just dust really is the concern. But props on the product and the service. Top notch.

Did not fit my vehicle

I went ahead and ordered these not knowing if they would fit into the sealed light housing. Well, I was rewarded for my courage, lol. They fit! The housing closes and seals shut with the retaining clip. Note on the install, one spade fits nicely into the female plug for the positive lead, but the other (ground) spade does not fit tightly in the round female plug. I flattened the round female plug gently with pliers and it works well. The retaining clip for the H1 bulb is somewhat difficult to get seated. The heat sink interferes with closing the clip, so a little creativity is needed. I used needle nose pliers to bend the clip abit for a tight fit. Will buy more for the high beam reflector.

Good bulbs will fit in even tight spaces but not as bright as ultra 2 as to be expected.

The bulbs supplied are without any disappointing surprises, and that is a big deal. The housings ÄúBegelÄù had a lose wire and a broken electrical adjuster connection on the reflector assembly. I would recommend finding some ÄúHellaÄù oem versions to anyone else doing this upgrade, I canÄôt guarantee how much better the light pattern would be with the Hella units, but thatÄôs where IÄôd start if I needed to do this again.
The result is about 400% better than the old headlights with the new led bulbs.
And bout 300% better than the stock h7 halogen bulbs.

These bulbs give off a great amount of light, especially when compared to old halogens. The only thing the bulb mount does not have the recess where original H7 bulbs have it, and then you have to bend the wire that holds it in place. This doesn't sound like a big deal, but on an old headlight assembly the plastic can crack easily while doing it.
That's why I gave these four and not five stars.
If they modify the mount these would be perfect.

Size is close to OEM bulbs and fit in the headlight enclosure, definitely brighter than OEM incandescent bulbs and produces a good light pattern, worth while upgrade.
