SEALIGHT X4I H4 9003 HB2 Bulbs H4 Headlight Fog Bulbs with Adjustable Lock Ring Cooling Fan Easy Installation

This is my third set of these, all Chevy's '11 2500hd, '18 2500hd and my '24 3500hd. Couldn't be happier with them. My welding company is out in the middle of nowhere in northern Michigan and the sometimes invisible whitetail deer are a huge issue at night. The Sealight LED's have been a monster improvement over the stock bulbs. They project a wider, brighter and whiter beam, not much else needs to be said. These LED's and Ranch Hand bumper on each truck saves us huge on insurance claims, sometimes monthly. I was cautious with my '24 because of all the complaining over "hyper flash" and them just not working, mine worked perfectly. Just do your home work right down to the wattage your factory bulbs use and match it to what you buy. Read more

I recently upgraded the lighting on my 2015 Jeep Grand Cherokee to the SEALIGHT X4I H4/9003/HB2 LED bulbs, and I have to say, they are impressively bright and perfect for off-road use. My previous halogen bulbs had a tendency to fail annually, prompting me to switch to LED bulbs to avoid the frequent filament failures. Key Features >> Exceptional Brightness: These bulbs deliver an outstanding level of brightness. It's like looking directly into the sun, making them ideal for off-road conditions where maximum visibility is crucial. >> Durability: LED technology in these bulbs eliminates the common issue of filament failure found in traditional halogen bulbs. This durability was one of the main reasons I opted for this upgrade, as I was tired of replacing my halogens every year. >> Easy Installation: The SEALIGHT X4I bulbs were quick and straightforward to install. It took me no time to swap out my old bulbs for these new LEDs, which is always a plus. Sorry to say I do not believe these are Street-Legal in my setup: One important consideration is that these bulbs are too bright for street driving. Their intense brightness can be blinding to oncoming traffic, and lighting up houses with floodlight brightness did not make me popular with the neighbors, making these LED bulbs unsuitable for regular road use. Personal Experience While these LED bulbs were a breeze to install and are fantastic for off-road adventures, their brightness is excessive for standard street driving. I currently use a different set of LED bulbs that are adequate, but I'm still on the hunt for an option that offers the perfect balance of brightness and street legality. Conclusion Overall, the Beyond Bright SEALIGHT X4I H4/9003/HB2 light bulbs are a great product for off-road enthusiasts seeking enhanced visibility and durability. They provide a significant upgrade from traditional halogen bulbs and are easy to install. However, I would strongly cation a buyer to consider the application for street driving due to their extreme brightness. If you're looking for LED bulbs that are street-legal and offer a bright, clear light, you might need to continue your search. For off-road use, these bulbs are hard to beat. Read more

I have purchased multiple different bulbs for my 2015 Nissan altima and these are the ONLY ones that actually really work. There was a class action lawsuit for the 2013-2018 Nissan Altima due to the headlights losing their reflection ability. It was almost impossible to drive at night/dark. I had to drive with my high beams on and still could barely see. Of course the "recall" window had passed. So, I was stuck with paying for all new headlight assemblies. I bought 2 other brands of bulbs and it made a slight difference in the brightness. I finally had enough and paid the money to get these bulbs. Best decision EVER!! I can finally see at night/dark. Which that is freaking priceless! They were easy to install. I did it myself. I highly recommend these bulbs. Especially if you have a 2013-2018 Altima. (You have to buy new headlight assemblies so they will actually project/reflect. The OEM assemblies lose their lamination on the headlight projector) Read more

Different brightness for either bulb. Quite long lasting, my car doesn't turn off headlights and i use it every day. Bought in 2022, and one just got dimmer. Looking for another replacement in 2026. Read more

Vast improvement over the halogens in my 2008 CRV. 20 minutes to install, taking my good old time. Probably could have done it in 10. Drivers side is very tight, so a little bit longer on that one, but it fits. Read more

The media could not be loaded. I have a 2014 honda accord. I spent the extra money for these and they didn’t disappoint. In my video the left side is the LED and the right is the original yellow bulb. Theres no comparison these are much brighter than the oem lights. Very minimal noise from the bulbs fans, but that’s irrelevant when driving. Fitment and Install was a breeze just plug and play. Read more

I got two sets. One set for dims and one for brights. They are very bright on dim, and incredibly bright on high. The only reason for 3 stars is they flicker all the time. If not for the flicker, they are very nice. Might not for other people Read more
