SEALIGHT H4 LED Headlight Bulbs, 9003/HB2 LED Headlight Bulb, High Low Beam, 12,000 Lumens High Brightness, 6000K Cool White, S3 Series

I got these to replace the factory halogen headlight bulbs in my 2016 Honda Fit, as well as a set of H11 lights for the fogs. The new bulbs feel like they are high quality, and the install was straight forward on my car. To my surprise, these headlight bulbs work in DRL mode as well as low/high beams with no flickering. The cutoff line could be a little sharper, but it is still very acceptable considering the housings were not modified in any way for these LEDs. I am very please with the color and light output compared to stock.I have uploaded some pictures of the factory low beams with fog lights, the new LED H4 low with H11 fogs, and LED H4 high beam alone.

One of the "traditional" halogen bulbs (SYLVANIA - 9003 (H4) Basic) in my 2002 4Runner burned out, again, this time in less than 12 months. As it turns out my girlfriend was complaining the week before about "those a$$holes with LED headlights" and so I figured, this was as good a time as any to try LED headlights lights out on my vehicle.The old headlights had a connector directly on the back of the bulb which fits a rubber boot at the end of the wiring harness. Pull off the boot, unclip the retainer and the old bulb falls out into your hand (or all the way to the ground, depending on where your hand is). That part was easy.The new bulb has a long cable hanging off of it. Shove it into the housing and you can clip the retainer just fine, but what am I supposed to do with this extra cable. It's clearly not removable, and it's got a big lump halfway along that likely holds some electronics. I plugged the boot from the wiring harness into the far end of the cable, but now I've got a bunch of wiring with no clear place to live. I used a zip tie to keep the extra wire from falling into the engine compartment and catching on something, but it wasn't obvious what I was supposed to do.Anyway, once I slammed the hood down, I turned on the car and BOY OH BOY ARE THESE BRIGHT. They're easily twice as bright as the OEM halogens they replaced. I'm not sure they're legal, they're so bright. But I live in a relatively rural area with a streetlight density of about one per mile, so having bright headlights is absolutely a good thing.Can't comment on the longevity yet, but it can hardly be worse than the halogen it replaced.

Install was pretty easy. Have to remove a small disk from the bulbs, install that disk into the headlight assy, then twist the bulb into the disk. Which is exactly what the instructions say to to do, if I would have read them before starting. Very bright, a huge improvement over stock, or the PIAA slightly brighter halogens. Haven't had anyone flash their lights at me, so I don't think I'm blinding everyone. Haven't had them for very long, so I don't know how good the longevity is. Was impressed enough to get a set of H11's for a ford fusion, and now looking to get a set to give to a friends '05 tacoma as a late christmas present.

Install was extremely easy like other sealight LED lights. I can tell the light is brighter and more white than the S1. It looked like it was a little higher angled up so I angled my head lights down just a bit more. I'll need to do an actual headlight height test when I have more time. But overall very clean looking. Only concern I would have is on the fans and hoping they last. But very nice looking.

Great, at least after the first week. Very bright with a good pattern. Some minor shadows on the road near the car, but not really a concern. The one possible concern is that the rubber seal for the headlight blocks much of the airflow to the bulb's fan. It will be interesting to see how that holds up when the weather turns warmer. The installation video talks about 'chipping' the rubber seal, but that doesn't really help for this issue because the seal rests against the clip that holds in the bulb and can not be moved 'further in' to give the fan more breathing room. One last note - it required quite a lot of force to turn the bulb to the right orientation when inserting it back into its collar (after reinstalling the rubber seal). Make sure that you do turn it sufficiently (all the way) or you won't get the right beam pattern.

I have been running Sealight bulbs for the last 5 years. I love them. They work wonderfully on my Tundras. They provide a nice clean focused beam with no weird cast off like many other LED bulbs. Unfortunately, after installing these lights a little over two months ago, the driver side low beam bulb has burned out on my drive home tonight. Normally I wouldn't fret since they aren't that expensive and stuff happens, but Toyota engineers screwed up bad with the design of the 3rd Generation Tundras and I have to take apart the entire front of the truck to replace the bulbs. I believe it is the fan cooled bulbs that create longevity issues. Unfortunately the non-fan bulbs are very difficult to find these days. I can't give these the high rating they probably deserve because they burned out so quickly. My last ones in my previous tundra were still going strong after 3 years. They even worked after I was sandwiched between a 4 Runner and a box truck last year. Great brand, this model just might be iffy.

They were a pain to figure out at first due to the seal and the adaptor. You gotta put the adapter on first then the seal then the light. For a Yaris ia 2017. They are very bright! You can twist to adjust them to align them just right to get optimal performance... should have stared with theses in the first place. The look pretty high quality.
