SYLVANIA H11 SilverStar Halogen Headlight Bulb, High or Low Beam, 2 Bulbs | High-Performance Headlight and Fog Light with a Brighter, Whiter Light for Improved Contrast and Visibility

Was very satisfied with these lights

I just installed these on a 2013 Cadillac CTS and they are brighter and whiter than the OEM (very little night driving on my Mom's car, so really OEM.) I can tell you to install on that car isn't easy because you have to remove part of the bumper but that's hardly the bulbs' fault. Others complained about these bulbs burning out too fast but you have to put it into context. These bulbs are brighter and whiter than the entry level lightbulb because they burn hotter and likely have a different gas mixture inside the bulb than whatever you're used to. There is an inverse relationship for all incandescent bulbs between lifespan and brightness. More life, less bright. More bright, less life. Using these bulbs >will< increase the temperature inside your headlight housing compared to more typical, less bright bulbs. This can be very bad if you frequently drive several hours per night without any cool down, or even if you're in a very hot climate. The hotter the bulb is, the quicker the filament will burn away. So these driving conditions could burn the bulb out before it's rated number of hours but it is actually what's expected. If you have an older car and these driving conditions, it is possible the excessive extra heat generated can cause physical damage to your car's electric or surrounding plastic. It's very unlikely you'll have that problem with any car in normal conditions. Check with a pro if in doubt. If you do a lot of night driving and want bulb longevity over brightness, whiteness and down range illumination then you might try one of the 2 cheaper bulbs made by this company. If you want better night driving performance lights there is 1 bulb above this by this company that does it, but beware those bulbs last for less time than this one. You'll get more runtime hours out of this bulb if you drive less than an hour at a time with lights on and do a 30 minute cool down between multiple trips. It's just the way it is with these bulbs. If you want the best of all worlds and will spend the money, some LED headlight bulbs on the market claim to offer both longevity and superior performance. Personally I find the light frequency of most LED headlights to be a strain on my eyes.

I had put LED bulbs in thinking I would get a brighter look down the road. Turned out I could drive with my bright lights on and nobody would even flash their lights at me. Decided to go with the Sylvania H9 and H11 SilverStar bulbs and what a difference. The low beams are now brighter than when I had the LED lights on high. Clicking to high beam lights up the road very well and for a long way.

I gave 5 stars since this is a product review, but you need to know that Amazon in all of their wisdom decided to ship glass light bulbs in a paper envelope. I have see other reviews point this out, so just know your ability to get a non-broken product is risky if this is how they ship them all. But to the product it was a great fit for the H11 lights and overall they work fine. The existing bulbs were the stock OEM and one burnt out. I replaced the bad one with this new SilverStar and honestly it looks pretty much the same as the OEM. I ended up replacing both to save the hassle down the road. But reading the difference in the Sylvania lights I would have thought the SilverStar to be a much better bulb, but looks to be the same as OEM. Was expecting more from the SilverStar based on the Sylvania information about the different levels. Was planning to go with the higher level than this one but Amazon was like a week to get it here, so I think I am glad I didn't spend the money for that.

These aren't the brightest nor are they the most expensive or cheapest but they're pretty good solid headlights I would say if you need these go for it they're definitely worth the price

These bulbs only lasted 9 months. They were moderately brighter that my previous bulbs. Disappointed in the longevity. Will not buy ahain

Buy the pair. I replace right and left at same time even though only one is burnt out. Easy to install on our Volvo XC60

Huge improvement over my original ones. Wonderful visibility. Arrived quickly and in perfect condition.

Nice and bright. About same price as store.

These Bulbs are nice in the night and project about 40' further than the stock ones in my 2008 chev hd

Waited to write the review to see how long they will last. It's been more than 7 months now (including a cold Canadian Winter) and these Sylvania H11 SilverStar High Performance Halogen Headlight Bulbs are still going strong! : ) I really believe anyone who reports that these halogen headlight bulbs don't last is because they're not aware that any oil on any halogen bulb will cause them to burn out prematurely. Yes, this includes oil from your hands! Once the old bulb is removed, I put on a fresh pair of disposable gloves (nitrile or latex) and install the new bulb. If disposable gloves are not available, washing your hands thoroughly and using a clean rag to handle the bulb will work. The trick for these bulbs to last long is to make sure nothing oily touches the glass. I hope this helps.

They were easy to install and so far appear to improve nighttime vision.

The package was delivered same day, as promised. The light does exactly what it is supposed to. Haven't been pulled over for a missing headlight. I would definitely recommend
