LASFIT T3 WT21W LED Bulb Backup Reverse Light WT21 WT21W/7W Canbus Error Free for 2022 2023 2024 Ford Maverick XL XLT Lariat Accessories, 2021 2022 F150 F250 F350 Xenon White Anti Hyper Flash (2pcs)

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!

Brighter than the oem lights no hyper flashing.No problems with installing.

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.

These are nice and bright. Much better than stock bulbs!

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.

LASFIT T3 4257 4257NA LED Bulb Switchback Built In Resistor Front Turn Signal Light for Ford Maverick Accessories XL XLT CANBUS Error Free White Amber: Product arrived quickly and in good shape. Like other reviewers have said, all you do is lift the hood of your vehicle (a 2025 Ford MaverickXLT for me) and replace the turn signal bulbs. All it takes is a quick twist to unlock the socket, pull out the old style light bulb and replace it with a LASFIT unit. BE SURE TO TEST THE LASFIT AT THIS POINT! Mine hyperflashed so I unplugged it and plugged it back in reversing the LASFIT unit. No further problems! They are sensitive to polarity. Repeat the process for the second turn signal bulb and you are good to go. They are MUCH BRIGHTER when signaling a turn. My neighbors have verified that my turn signals are much more attention getting now. The change from a low white light to a bright orange light draws peoples attention. I’m waiting to see how long they last. Other LASFIT products I have installed on different vehicles have always been very good.

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.

Worked as intended.
