T20 7443 7444 LED Switchback Bulbs

I bought these a while ago back in early 2018 for my 2016 mustang gt premium. They worked great until I took them out for the opt7 sequential turn signals. Well I popped them back in because I had the opt7 sequential turn signals fail on me multiple times and I’m done not having a unreliable turn signal. And well sure enough when I popped these bad boys back in after sitting in the stock turn signal housing for over a year they work like they should. And they match the tri bar why better than the opt7 6000k. These are like a 4300k-5000k light temp. I’ll never buy anything from opt7 ever again. Horrible customer service and they wanted me to pay for shipping for the return and then on top of it all wanted me to pay for the new set up front and if they deem they are warranty worth they will issue a refund weeks from now. They are in the trash where they belong. I’m Done dealing with them. If you’re on the market for something different from stock get these. They are cheep, bright as hell “brighter than the opt7” and reliable from what I can tell. Plus one day shipping if not same depending on your area. Only good thing I got out of the opt7 was the resistor so my interior turn signal won’t sound like a running horse when trying to turn. At first years ago it didn’t bother me but months later it got real annoying so using the opt7 resistor on the stock wire harness worked great and the turn signal is normal.

These were exactly as described and actually worked better than expected. On my 2005 BMW 330ci, I used these to replace my front turn signals. I already had load resistors and had intended to use them...but I didn't have to! I simply plugged them in and got no hyper flash or warning lights on the dash as I had expected to be the case. They are bright, seem well-made, and fit snuggly in the socket. The color output is great. They are longer than most 7440/7443 bulbs so in some vehicles it does push the bulb past the focal point of the reflector/lens. However, because they are so bright and designed to provide over 180° field of view, it is kind of negated. As someone who has owned many, many sets of switchback bulbs and who tends to have a tendency to be picky, these are just great bulbs and they are priced reasonably.

Actually ordered these by mistake but I’m pleasantly surprised. I intended to order ones with the built in canbus system. These do cause hyper flash but install some resistors and you’re golden. Amazing deal for the price and I’d buy them again.

Look great and very bright!

I purchased these Alla Lighting LED's for my 2020 Jeep Gladiator, which came with halogen lighting from factory. On the Gladiator, the front lights consist of a DRL & parking light combo in one housing (using a 7443 dual-filament white lamp), while the turn sig's are a separate lamp (7440A single-filament amber lamp) in the adjacent housing. My intent was to use these LED bulbs for the DRL/parking lamp locations, and they do snap right in to the bulb holder, as designed . HOWEVER, once they were installed, I discovered that the DRL's were amber, and the parking lights were white... just the opposite of what was anticipated (and what is the norm for forward lighting). I debated upon returning them, but decided a simple modification the the OEM wiring (at the lamp socket) would correct the problem. I simply swapped the two "hot" wires feeding the socket, which then made the white light come ON in the DRL mode, and the amber light come ON in the parking mode. There are 3 wires at the socket: Ground wire (black); DRL wire (white/yellow stripe); Parking light wire (white/purple stripe). Swap the white/yellow & white/purple into the socket. Sooo... while Amazon says these will "fit" a Jeep Gladiator (and indeed they do fit the lamp socket and light housing), they will not operate with the correct colors in the "stock" configuration. A wiring change should be done to make the light colors correct for the application. Not a huge deal, but please be aware...

You have no idea how many bulbs I've gone through trying to find working ones that wouldn't hyperflash. These are a+. I was even able to remove the nonsensical giant resistors from my wiring, these bulbs didn't need it and had perfectly working flashing and switches back to white when not turning.

I was really excited to get these . What a let down. I installed them. Turned them on and they were really bright and they looked great until I started it. The moment I did they started flashing amber. I have my DRLs enabled on my truck. The only way they would work correctly is with headlights on all the time. Returning them right away

Works great as a turn signal bulb, but could not get the white light to work, maybe it's a feature my vehicle does not have? I LIKE, LOVE hyper flash, it makes my car stand out, shows folks I'm changing lanes, so these caused hyper flash and I LOVE IT! Just wish I could have gotten that white light, switch back feature to work.

great product what a differance

Not error free. Not compatible with cadillac, chevrolet, or Mazda

light no working RAV4 2020

A bit too higher then should for a fit. Hits the lense and wouldnt lock. Too fast blinking to be called normal or pleasant : need additional controller to line blinking issue. Bright for sure- that's the positive thing.
