T15 LED Bulbs

Installed LED switchback bulbs and the DRLs are very bright compared to stock, with a white output. The amber turn signal switches quickly and is easy to see even in direct sunlight. Fitment was simple just plug and play, and everything worked without hyperflash on my setup. Improves safety as people can see you easier. Overall, a good quality and solid upgrade for the price over factory bulbs mainly for brightness and appearance.

I installed these on my 2022 Kia K5 GT-Line FWD, and they were one of my favorite upgrades, they performed flawlessly the entire time. Installation was straightforward, and I had zero hyperflash, no error messages, and no warning lights thanks to the built-in resistors. Compared to the factory halogen turn signals, these are a huge improvement. The amber color is crisp and modern, and the brightness matches the intensity of the K5’s factory LED daytime running lights almost perfectly. They complement the full-width rear LED light bar really well and give the car a much more premium, factory-like appearance. This is actually my second purchase from AUXITO, and they’ve continued to impress me. In my experience, they’re one of the best aftermarket lighting brands out there in terms of quality and reliability. If you’re upgrading your factory halogen turn signals, I’d highly recommend making these one of your first modifications. You won’t be disappointed.

We have only had this in a few days but the light is clearly brighter than the stock bulbs. Installation was very easy and the fit was tight and secure. I will update this after a month. We have not had the chance to use it in the dark yet. Down side of not getting dark until 8:30 PM

Installed these AUXITO 912/921 LED reverse lights on my 2021 Toyota Tacoma in October 2024 and got about 20 months of service before one bulb eventually failed. Interestingly, the failed bulb looked cosmetically cleaner, while the working bulb showed more oxidation and aging. After inspecting both bulbs, I found no burned LEDs, corrosion, or obvious signs of damage, suggesting the failure likely occurred within the internal driver electronics rather than the LEDs themselves. I also noticed that the new replacement set appears to have some design differences, including a different heat sink and updated circuitry. That said, it’s hard to know whether these are true design revisions or simply variations between production runs, and the new black heat sink actually looked a little rougher out of the package than my original set. Overall, these lights provided excellent brightness, greatly improved nighttime reverse visibility, and lasted long enough that I chose to buy the same AUXITO bulbs again. For the price and performance, I’m satisfied with the value and would recommend them.

Out of the 10 different built-in resistor bulbs I've tried, the dual function Auxito bulb with 2 chips on each side is considerably better than everything else. This single function bulb would be my 2nd choice and I'll give some quick notes on everything I tried and how Auxito could make these even better and I really hope they do because some of us would greatly benefit from even brighter bulbs. Even though my front bulb was a 7444na it's a single function blinker only. The rear WY21W is also single function. You can use single or dual function bulbs in both front and rear in this car. I give 4 stars for both Auxito bulbs even though the single function one is more 3.5 stars. The dual function one on this car has enough intensity to where it fills the reflectors to the point where it makes the housing lens look like a solid light and no other bulb even came close to that. The single function bulb gives off sufficient light output you just lose the intensity from only having one chip on each side to hit the reflectors. There are a few ways these could be improved. Having a chip on the end would help people like me for where I drive. I have a lot of turns off roads with corners and hills. Having a chip on the end would help the flash be seen around the corner or over a hill before the person behind you physically sees your blinker. If that's not an option on this bulb, there are 2 other options that might help. Either put 2 chips on each side of the single function bulb or make the dual function amber bulb to where all the chips light up for the blinker function. Any of those options would be perfect for some of us. I'll jot down some notes from other bulbs I tried. Zonbeam had a good idea but would need 2 chips on each side to fully light up the reflectors. Their bulb was heavy and didn't fit snug in the front. The dual function Zonbeam was fine in the rear w21w socket but the 7440 single function one had a nub I would have had to grind off to fit the w21w socket. That bulb projected the darkest light onto the garage door so I'm guessing it would have shined the farthest but these Auxito dual function bulbs are brighter to look at. Oxilam bulbs worked but I could feel the fan each blink plus the chips are arranged weird so they reflect differently in each housing making it appear you have 4 slightly different bulbs. Doubt it's noticeable in real time because only one side is on at a time but I have OCD and I knew it was different! Oppulite worked, were quiet, and cheaper but not nearly enough light output for me. Lasfit T3 were in the middle of brightness level and worked but I think I just got bad bulbs. 3 of 4 started hyper flashing not long after putting them in. Pretty sure the resistors went out but they refunded me. Oh Lasfit does have a really good base of bulb though, they click into the sockets and won't fall out. These Auxito are safe from falling out too, these aren't heavy like some others. Evntyps bulbs somehow are barely brighter than Lasfit and that surprised me because they have 28 more chips. Alla Lighting bulbs were the least compatible with this car. Super loose in the front but did fit snug in the rear w21w socket. Light output wasn't anything special plus they changed from the bubble chips they used to use to flat chips. I do recommend either of these Auxito bulbs even though I think the dual function ones are better in this car and I do hope they make one with the same intensity that also shines further. Hope this helps people and thank you.

Absolutely amazing and very bright. True to amber color. I ordered two pairs so I can replace the white stock light one also. It looks so much better with it being amber all the way across. They are kind of difficult to start in the socket but just flip it around a few times and give it a wiggle with a slight push. Remove the 10mm bolt and the small plastic push button fastener and pull back the plastic fender to gain access.

These are awesome! On my 98 ranger they turn off in-between blinks if my lights are on which makes the blinker more distinct. On my 95 Escort they are a really nice upgrade in brightness and vibrance which is exactly what I wanted. I had no issues with the size and fit, but they do get QUITE hot, so definitely fully installed them before checking brightness haha

I'm writing this review on 6/16/2026, and I'm disappointed to say that these only lasted 16 months. I purchased them on 3/2/2025, and initially, they functioned perfectly, providing super bright light that made passing cars aware of me reversing. Unfortunately, both sets started flickering, and troubleshooting didn't resolve the issue.

Love it , very bright! Looks good. Installed it yesterday, still need to try it on for the rest of the time.

Fits perfectly and the visibility is also good compared to a stock (halogen) bulb

Aluzan muy bien y de fácil instalación

Works great in my 1997 f150. Nice and bright, no hyper flash issues at all. Only built in resistor turn signals that have worked with no hyper flash for me.

Extra bright
