9005 LED Headlight Bulbs 12000LM High Beam or Low 6000K Cool White 4-Side 360 Degree Lighting Extremely Bright HB3 Xenon Halogen Replacement, 5 Year Warranty

These 4-sided headlight bulbs are brighter than the stock halogens, no doubt. The seller is a good outfit, as one of the bulbs from the first set I ordered did not work and the seller quickly offered replacement. There are definite pluses and minuses for my application tho. I put these bulbs in a Olds Custom Cruiser, which maybe has some of the poorest light output design headlamps of any car I've driven. Knowing this, I thought if two sided bulbs were good in my other car, 4-sided should be even better. That did not quite work out for me. These bulbs do cast out a tremendous amt of light, but that light is kind of everywhere forward on the car and does not put enough light on the ground far enough from the car. It took me a while to find the "sweet spot" for these bulbs - make sure the wire points down on the bulb to ensure the light elements are in prime position, then aim the headlights. I had to aim mine down slightly to keep from getting headlight flashed by oncoming cars. This limits how far away the lights can be used to shine on the road in front.The metal connection elements in the plug are a little fragile and easy to break loose. It is hard to not bend them out of place when trying to plug in. And if you plug wire is not pointed straight down, you will cast a strange pattern of light - I had a pole shaping of light coming out of a headlight with the bulb was slightly turned.In all, these LED bulbs work and cast a lot of light. I just wish the light could be aimed more effectively in my light housings.

I only gave 4 stars for the following reason:I purchased these headlamps in April 2019 for a vehicle that is used part-time. 90 days later I noticed that one of the headlamps was not working. There is a 12 month guarantee and a 5 year warranty, BUT, there is no way to get them to cover the guarantee. I called Amazon and spent 28 minutes on the phone as the young lady tried to solve the issue to no avail. She had no way of contacting the seller or the manufacturer. Don't throw your money away with these headlamps!UPDATE: The company had an email address to contact them. I got a response from them about my issue and they were very quick to get out a new set. All they required was for me to cut the wires to the lamps and send a picture to them showing that. The new lamps arrived and I have not had a problem since. I assume the first set was just defective.

Two years ago I bought a pair of amazon's choice 2 side LED light bulbs. The result was disappointing. It is worse than my halogen bulbs. The 2 side doesn't work out well for projector HL. Then I bought xenon bulbs. They are very bright. But the life span of xenon is a concern and sometimes the ballast fails to start the light bulbs.These 4 side LED bulbs work pretty well in my projector HL. The first picture is from my minivan's reflector HL. They are much brighter than the original halogen bulbs. The second picture is from my sedan's projector HL. In the left is from this 4 side LED bulb. In the right, it is from the xenon bulb. It is not brighter than xenon, but still much better than halogen. I have no issues after 6 months of use.Update July 2020. After 18 months, both light bulbs were broken. This is shorter than I expected.

Another great kit overall (3rd I've purchased from them), however the 9007 bi-xenon kit could use some major improvements with install directions. Someone less knowledgeable either automotive wiring and HID systems may struggle with install. Harness quality and install supporting parts were very well made and appear very high quality. Would've given 5 stars if the install instructions were better, but overall the performance and whality of components is top-notch! Best HID systems on Amazon for the price in my opinion. Highly recommended you can't go wrong with these guys. A++

I truly wanted the ultra white but they still look good and for the price I can’t complain.

They are super bright, assembly of the bulb was sub par, had to flip my bulbs the wrong way to work, in which I just re-wired my pigtails so the bulbs would lock in. I have had one bulb already go out, only after 3 months, maybe 4. Although customer service is pretty damn good. I probably would buy again, just for the value for dollars.New Edit, so these bulbs are great for the first few months... then one will dim and burn out. So I decided to contact to just do a warranty return. Well guess 12 month guarantee doesnt mean a damn thing. 12 months and a 5 year warranty all that means is they will replace the bulb after you send them a picture of the harness cut. So that is what I did. If I have another burn out, I'll have to escalate this further. All while on the market for a replacement set.

I like the cooling fans on the lights. They do a great job at not allowing the led's to overheat. The lights are super bright and are a great replacement for the stock halogen bulbs.

So far so good. They didn't go in without a little bit of elbow grease, but seem to be working just fine. Had to get a little tricky with the rubber boot that covers the light.
