CANBUS 7440 LED Bulbs Amber Yellow for Turn Signal Lights with Built-in Resistor Anti Hyper Flash 7440NA T20 7441 W21W WY21W Exterior Light Blinker Bulb Replacement, Pack of 2

I ordered this for my 2013 Ford F-150 STX 5.0 for the reverse lights. They are a direct fitment, they fit perfectly inside the housing. Installation took a few seconds. They are very bright and the light output is even. They are good quality and have zero flashing. 10/10 recommend

Nice and bright compared to the stock bulbs on the truck. Very easy to install, simple plug and play. Will see how long they last but so far they are working well.

Great to find these to resolve my hyper flash I have been tolerating since converting my 2007 Chevy Tahoe over to LED last year. You have to do front and rear turns on each side to resolve the hyper flash. I did one side and it flashed normally. The other side still hyper flashed until I did both the front and back on that side. The back is really easy, two screws on each side then gently prying the push in plastic closest to the rear fender and housing comes right out. The front is much more involved. Remove top 10mm bolts on light housing and 10mm bolts on the top of the grill to loosen it allowing the headlight housing room to come out, then front of fender liner on each side 2 7mm bolts and a few push clips then a 10mm on the borrow of headlight housing and 2 10mm bolts just inside the fender liner and remove the plastic bracket that supports the front ‘bumper’ to loosen it up allowing the headlight housing room to slide out. Then once bulbs are change reverse the process. Note: the headlight housing is in there pretty tight and requires some gentle work and prying, don’t forget it is plastic so go easy on it. I like the fact that the include built in resistors so I do not have to manually install them in he circuit. Much brighter than factory bulbs that came on this 2007 Tahoe. I would recommend while you are in just do all the bulbs at once - daytime runners, turn signals, side markers and high and low beams since it is a big process to get to the back of the housing. Same with the rear change out side markers, turn signals and brake/runners. Red leds are best for rear and amber and clear where applicable on the front and of course white bulbs for reverse and headlight bulbs.

Got these while doing a LED conversation on my 2018 Jeep Grand Cherokee. The install was a pain in the a--, but that was because of the car, not the bulb. Worked like it should, looks great, crisp and bright. Hopefully they last. So far would recommend.

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.

I'm using these lights in my vanity mirrors or the mirrors under the visors. At least I think they're called vanity mirrors... 😊. But be aware these are very bright for that and if you do use them for that, take a long time to get accustomed to. I have come to love Auxito bulbs for their quality, longevity and their customer service. They are the brightest and clearest for color bulbs I have ever used used and they always fit my applications for ease of installation the best of any bulbs I've used and I've had the least complications with trouble codes too. And most of all customer service will always be there to help you out. They have never let me down yet amd they are always so friendly and supportive as in behind you too. I have had to had an LED headlight replaced by them recently and it went flawlessly I was sent a pair to replace one of a set of four that I bought and I am so grateful too btw. I thought it was more than accommodating. As I said, very friendly too! You don't always get that. Thank you for reading and thank you Auxito, Erin V :-)

I had led bulbs in my turn signals before but all of the sudden the driver's side rear started hyperflashing and the light was getting dim. I replaced them with these and the hyperflashing stopped and they are working great, much brighter than the old one too! Highly recommend these for the rear turn signal (2012 Pathfinder).

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

I just replaced the rear turn signal bulbs of my 2024 Toyota 4Runner Limited with these Auxito LED bulbs. I ordered these bulbs since they are the shortest in the market and do have a fan and metal body for good heat dissipation (to avoid hyper flashing once they heat up). They work great with no errors. No resistors are also required. You will not be able to install these LED bulbs through access door within the car. You will have to remove the whole tail gate light unit. There are YouTube videos online showing how to remove the tail gate light unit so watch them before you order these LED bulbs to make sure you are comfortable with removing the tail light unit.

Very good

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.
