SYLVANIA - H11 SilverStar Ultra - High Performance Halogen Headlight Bulb, White, 2 Pack

Best performing low beam headlight bulb for the 2006 Buick Allure CX 3.8L V6. This is an H11 replacement bulb pair for my low beam headlights. I got about 2 years out of my last pair of the exact same make and model from Sylvania. They provide a good colour rendering index of projected light under all driving conditions including snow ❄️. It projects light really far and clearly for night driving. It is also a good colour temperature for the eyes. It is a little bit challenging to replace the low beam headlight bulb for my vehicle but I have the procedure down pat so it is easier now. I recommend this exact H11 Sylvania bulb as a replacement because you should never skimp or compromise your ability to see clearly when driving at night. It is the best in their lineup of replacement headlight bulbs. Always replace headlight bulbs in pairs!!! I don't recommend LED headlights because they may also throw ECU codes for incompatibility, unless you're certain they won't from the manufacturer. Double check this functional requirement with the manufacturer before purchasing an LED replacement headlight bulb pair. Always replace headlight bulbs in pairs!!!

I wrote the following post but felt I needed to come back and correct it. After I had made that post, I went to the actual Sylvania store site within Amazon and submitted a complaint. They got back in touch with me by email and requested my proof of purchase. Without me making any demands, they apologized, acknowledged that some problem products slip through the inspection system and sent me a replacement light bulb! I consider that excellent customer service! I have been using their bulbs for years (this one and the next price level down) and have always been pleased with the product. Now I am impressed with their customer service as well! I changed my rating from one star to five! PREVIOUS NEGATIVE POST: I purchased a set of these in December of '25 and the bulb had burned out buy mid-April of '26. These bulbs are too expensive to only last 4 months. They SHOULD last at least a year or two. NOT! And there is not recourse if you buy them on Amazon. Good luck finding someone to help when you buy a bad product.

These are a great choice for headlights. Sylvania makes some good products. This one is one of their higher level headlights. A very nice and clear white light. Great brightness and allows you to see further down road than some of the other headlights out there. I feel like it’s a very nice addition to my car. Feels like expensive bulbs for a great price. Changing my old ones out was fairly easy. Just a tight spot to fit my hand into. But the pop in and lock on just like every other bulb out there. Plus they are $20 cheaper than getting the same ones from my local auto parts store. You won’t be disappointed in this decision.

My OEM bulb decided to call it quits, prompting me to give the Sylvania H11 Silverstar Ultra a shot. Verdict? The brightness goes above and beyond, illuminating the night and revealing details I didn't know were there. I attached a picture for you to witness the light for yourself. While I don't have a snapshot of the OEM bulb for a side-by-side, it is obvious to me that these Silverstar Ultras outshine in terms of light volume and crystal-clear vision. Now, the only hiccup is, despite being touted as 'WHITE LIGHT,' it's more of a subtle, cozy glow—maybe around 3000K to a max of 3500K. That is the reason why they do not get a 5-star! At this moment, I do not know how long the bulbs will last. Just hold my hope!

Only bulbs I use they are awesome and bright without blinding every other car like leds do. Last super long never have had issues
