Really bright white / amber and great build quality
2025 Maverick XL. Switch backs worked perfectly. The white lights look awesome and help bring the XL up a bit. The amber turn signals are bright and flash on and off really nicely. A lot sharper than the halogens. Easy install. If they don’t work after install try taking the bulb out and flipping them around. The polarity matters as I found out. I don’t know if there is an automatic program or setup period, but the DRLs didn’t work immediately. when I went for a drive a few hours later they did. Great value and build quality felt better than cheap leds bulbs. Fingers crossed they hold up for a year or more!

Can do emergency lighthouse duty!
These are VERY bright. Great for seeing in the dark, but I wonder if they're too bright for whomever may be behind me. Installation is pretty easy - it's just changing a light bulb. No problem with CANbus codes.

Must have!! Great quality and even better customer service
I’m beyond pleased with this company-seller. My first order wasn’t as expected. Seller contacted me sent replacements and took care of me. I’m very happy with the customer service I received. I installed my new replacement and couldn’t be happier. Happy customer! I do recommend this product with great service.

Extremely bright but terrible fit in W12 sockets
Update 13Dec2025: Passenger side burnt out completely after months of figment issues. Tried glue, new OEM sockets and new OEM wiring harness for my reverse light. Periodic issues the entire ownership experience. They are too heavy for cantilever mounts with this socket. Design flaw. They burn out very quickly. Quality issue. For $54 I DESERVE BETTER. I’m not sure if Lasfit stands behind their products or not but Indonthave anything good to say about these bulbs and wouldn’t recommend their products to anyone based on this experience so far. Old: I use the white version for my reverse/backup light. Fits the W12 socket on my 2021 Ford F150 halogen tail light housing. Extremely bright. Of the six different bulbs I’ve tried this was probably tied for the brightest *AND* it fit the OEM socket securely without any of clipping or grinding some of the other style bulbs would require. Note: My driver side rear light is an OEM housing and my passenger side is a Chinese copy aftermarket rear housing that doesn’t have quite the same quality of socket clips and lacks the clamping power of the OEM clips. After fussing with the bulb coming lose in my aftermarket passenger side rear light a couple times I finally fixed it by smashing the bulb into the clips and then shooting a fair amount of hot glue into the socket voids. I didn’t want to use super glue or anything like that in the event I eventually need to replace this bulb. Works perfectly now.

Perfect fitment on 2019 f150, enhanced visibility
Changed all the factory halogen lamps out on the front of my2019 f150 to Sealight LED lamps (low,hi, fog & switch back turn signal/ daytime running lights). The lamps were all a perfect fit. The easiest installation I’ve found/read was by leaving the headlight assemblies in place and replacing the old halogen lamps with the led lamps through both front wheel wells. I’ve noticed a dramatic difference in brightness and quality when driving in the dark. Simple plug-n-play swap out without any flickering. No more HID’s and driver boxes to deal with on this upgrade. Only had the lamps installed for 3 weeks so I can’t comment on the longevity of the lamps but so far I’d highly recommend these if you are looking to not only see better but also give your truck more of an appealing look.

Nice visual addition, low power on the white light. DRL's at most.
These are pretty good replacements for the stock filament bulbs. The switchback feature is nice. They do add a good look to the front of my 2025 Maverick XLT Hybrid. They do a great job at making the front look more "complete" in my opinion. However, the switchback feature, the white is rather dim. It's not anywhere near an average set of fog lights. The turn signal, bright as could be. Reports of the lights looking "pink" is simply the white and orange combining. It does kind of look pink as the white never turns off. All in all, the lights are a nice cosmetic upgrade. Kind of expensive for glorified turn signals however. I've had a few different bulbs from lasfit and they've always been good quality. However, I may look for something different for these turn signals. Wish there was a decent way to add fog lights to the truck, but these switchbacks don't give off enough light to qualify.

Perfect fit and definitely brighter than OEM. Just installed tonight I’m hoping they last a long time.
