SEALIGHT H4 9003 LED Bulbs, 24000LM 100W 600% Super Bright, 6500K Cool White, HB2 Bulbs with Adjustable Lock Ring, LED Fog Light Bulbs, IP67, Pack of 2

I've only had them for a couple days, but the install was easy. Only had to slightly adjust the high-beam bulbs in my 2017 Honda Civic Ex-T sedan. Quiet, haven't noticed any electronic interference, and very bright. Skip the S1s, and X2s and get these. I haven't been flashed by anyone. I know they're aimed properly, I checked with a wall. Beam pattern is perfect. I have projector low-beams, and reflector high-beams.My only concern is the warranty, and longevity. Seems like the warranty is only 90 days. How can Sealight say the X3Ss last over 50,000 hours, and only offer a 90 day warranty? If Sealight really believed that, then why doesn't the warranty length reflect that? I read something that might indicate a 6 month warranty period, but that's unclear, and still not great. That doesn't inspire confidence. Had the warranty been at least 2 years, then I'd feel the manufacturer was confident in their reliability. I don't want these to burn out in 6 months, or 1 year. I'd like to get at least 3 years out of them. In the meantime, I've decided to keep my old halogens in my trunk, as a spare. Never know if these are gonna die during a road trip, or long night drive. Don't wanna be out of town with a broken headlight.I was going to give 5 stars, but I think 4 stars is the best I can give. This is due to the lack of confidence I have regarding the longevity of this product. I'll come back and update this review if any significant events happen with these bulbs.

The beam pattern stays the same but the brightness increases significantly. I would not hesitate to buy these LED bulbs again, they are bright and increase visibility significantly. This is the second set I have purchased and am very happy once again. Pro tip: buff out your plastic lenses to allow your beam pattern to be correct if you have older yellowed lenses.

These lights are very bright! Everything went together fine, although since the assembily mounts in a rubber groment, it's not clear how to know if they are rightside up, upside down, or sideways. I haven't had time to investigate as I have recently diagnosed with cancer and am getting ready to start treatment. Tried them out at night, and it appeared that one beam was sideways. At least they're working!

There in a 2017 Ford Edge SEL with projector headlight assembly. The pictures are in the most ideal situation, neighborhood roads at night. Bright overall and do the job. Not extremely bright on the highway or when other sources of lights are around. They are not spotlight bright in projector assembly's but they get the job done very well. Note they would be alot brighter if you plan on putting them in a reflector headlight assembly.

I like these a lot, so far they’ve been the best LED bulbs I have actually installed on any of my vehicles. Highly recommend these.

These are my go to LEDs from now on. Very bright. One failed after almost a year so I contacted them and the set another set hassle free warranty claim

The bulb is easy to install and, it have a high bright

Update. Company did me right and are sending me what I need! Zero complaints. Excellent customer service!High beams don't fit. Pretty mad about it

Easy install, bright! High and low beams, not too noisy. Flicks a little on the jeep Jk but barely noticeable. Would buy again and recommend to Family and friends! Should of changed my oem bulbs with these sooner!

It would be nice if few more meters of length (light)these bulbs can cover.

2016 Honda Civic et 2005 mustang

I bought them, installed them in a few short minutes. They’re incredibly bright ., slight flickering that is hardly noticeable. We will see how long they last.

Great customer support and communication, nice and bright good pattern. Unfortunately it did not work for my frontier 2017, DRLs were not compatible even with a decoder, I decided to keep the lights because they are a great improvement over my OEM,s.
