Osram makes a very high quality product and the Night Breakers are no exception. Replacing the HID bulbs are usually a straight-forward process but, thanks Honda/Acura for requiring the removal of the bumper cover on your vehicles to replace the bulbs - what should be less than 1 hour will take closer to 5.
Overall, the new bulbs provide great light and I expect them to last a long time as Osram makes a great product.

Did some research before buying these. After one of my OEM bulbs died after 8 years, I first got sticker shock at how expensive good branded HIDs cost. I had Osram Xenarc 66240 original/classic version on my car and it seemed too expensive to replace at $85. So initially I cheaped out and got some cheap Chinese ones from the big A for around $20. Those bulbs were much dimmer than the Xenarc, and had a bad green tint to the light, even though they were a lot brighter than halogens. The lower intensity highlighted the imperfections in the projector and the beam pattern and I wasted a lot of time adjusting the aiming. After a week, decided to pony up the money for good lights and got the brightest bulbs available in the market. These were quite a bit more than the Xenarc classics, but BOY are they bright. They seem a bit whiter (cooler/higher color temps compared to the classic Xenarc). I'd totally pay 60 more for 8 ish more years of extra brightness. You can see everything. The best out there, miles ahead of other cheapo lights. If you care about visibility these are the ones to get, or at least go for the classic Xenarcs - your eyes will thank you! If HR had the ultimate/long life Xenarc model I may have ended up getting those instead, but you can't find them in reliable american websites just yet (I don't trust the big A or the big E auction place for original lamps).

I loved headlight revolution's service as well. Shipped the same day as I ordered, got free 2 day shipping and got here in 2 days after my order. I initially placed an order at another website (a reliable one from the USA) but they sat on it too long and only had free ground shipping. I called them and cancelled it on the second day after I placed the order since they didn't ship yet. HR is miles ahead, loved the service and I did verify at the Osram site that the bulbs were indeed genuine.

You can't go wrong with these bulbs. Get them if you don't care about the blue look, and have the extra money. Otherwise get the classic Xenarcs for a little over half the price of these and still get a MUCH better output compared to the cheap crap out there, or even the B tier bulbs.
