BIOLIGHT KM - H11 SUPER ULTRA RACING - OPTIMAL FOR HIGH SPEED DRIVING - Headlight Bulb, Halogen Light Bulb, High/Low/Fog Beam Replacement Bulbs(Pack of 2) (H11 SUR)

These are not bright white lights as stated on box or description. These are still yellowish lights and not much better than the regular bulbs you buy at your local auto parts store. That being said one worked good the other bulb started flickering a bit before it started smoking, I pulled out the bulb and it was scorching hot even black plastic was burning and I dropped bulb on microfiber towel because it burned my hand. Then the cloth started sticking to bulb. It was a pretty bad experience.

I have purchased your lights, and the quality of them is very very poor. They are very dim. It is very difficult to see on a street where there aren't any street lights at all. A person driving needs to use their bright lights in order to see driving down the street. It is very difficult to see people that may be walking down the street without the bright lights. I rated the quality of the lights a 1 out of 10.It is very difficult to install the lights. The whole entire front end of a 2009 Chevrolet Malibu has to be gently removed in order to replace the lights. Then once the lights are replaced, the lights are so dim without using the bright lights.

as bright as your eyes may fool you into thinking they are. If you are looking for white and cheap these are it. A bargain for that aspect. I can't comment on longevity yet. But I suspected they were not quite as "bright" as my Sylvania Ultra's... but whiter by a noticeable amount-not a landslide but noticeable. But driving at night the Sylvania Ultras in H7 in my projector low beams provided more light. I put these in my high beams which are reflectors and they are even whiter than in the projectors. Overall a GOOD alternative to LED's which in an H7 with those ridiculous aftermarket clips are a struggle to install-especially in Mercedes cars. But overall not bad. If these were a brand name they would be twice the price. So yeah,,try them.

My daughter has a Mazda Cx7 and her lights were so yellow and dim to the point where I was nervous for her to drive the car at night or in rain.....got these headlights and oh my gosh it's been life-changing! I feel safe for my daughter to drive now!!

Ordered these replacement bulbs for my daughter's car. The price is awesome, and the lights are beautiful. They were insanely easy to replace, and they were delivered within a day of ordering. The price difference between these and the name brand is ridiculous, as these are just as good quality as the branded bulbs. The merchant reached out to me to make sure all was well with the purchase after I placed the order - something I feel shows excellent customer service. The lights are always on, and so far they haven't shown any sign of not being reliable lights. will buy this brand again if the need arises!

Took a chance ordering these bulbs--I had never heard of them and couldn't find reviews. I got them for a Kia Forte. Driver's side install was a challenge due to close quarters, but that is no fault of the bulb. Make sure you don't handle the bulb with your bare hands. Passenger side was a breeze. The bulbs fired up nice and clear and a very cool, bright white--no yellow at all. Very nice look.Update: Installed them at the beginning of October; both died within a week of each other at the end of July. Bummer.

Wow! These are much brighter than the stock bulbs that come with the Optima. At night, the front of the car is much more brilliant. No need for LEDs using these. Easy to install once I clip the front corner under body triangular panels. It’s about five minute job each side.

These are great- definitely brighter and whiter than a stock headlight. Don't expect a pure led white, but has a significant improvement on looks and functionality. I've tried led conversions but I prefer these as they don't effect my sensitive Volvo electrical system by throwing codes. Also as a bonus when they are not on you get a cool blue reflection from the headlight assembly. Longevity has yet to be reviewed.
