Nice and bright, they do hyperflash in my application but otherwise are quality 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.

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.

I recommend these. I am back to buy another set. These worked flawlessly for 2 years. Within a week of each other, both bulbs appeared to have a chip failure causing the Amber side of the bulb to hyper flash like a strobe light when it should of been solid. The white side still worked, but since the Amber side is always illuminated during the daytime in my setup I had to pull them out. These are still significantly cheaper, brighter, and lasted longer than some of the other higher end companies I have tried.

The media could not be loaded. Video is only for the ALLA LIGHTING 7443 LED Switchback directional bulbs.RECOMMEND for anyone who is looking for an inexpensive switchback that fits your application. The bulbs actually "snap" into place like they should, without having to worry about them falling into your headlight assembly. And they are longer than stock halogens, but they are not too long as to melt your headlight lens.I wanted a different look to my headlights at night, getting tired of the Horseshoe Halo's in my aftermarket headlight assemblies, so I disconnected them (I am not from Canada, and never plan on going to Canada). I DO NOT RECOMMEND anyone doing what I did, it's just my own peave with the GM Halo's combined with an amber parking light. This way I have NO amber in the front end at night, until I turn 'em loose on turns & light shows at car shows. Maybe some day I'll calm them down with resistors, but for now I obviously don't mind the hyper flashing.Also, someone told me my truck looks kinda purplish at night 🤷‍♂️ so the amber switchbacks add even more loudness to my truck's theme 👾 🤣

These DO NOT work as stated in the description for my 2013 Toyota Tundra. Both the DRL and turn signals are amber using the same circuit. Because the DRL's are on constantly, the required resistor needed gets to 350 degrees. The added resistor is designed to handle the momentary use of the turn signals which would not be an issue and allow the resistor to get so hot.I found a company from Washington called VLED and ordered resistor free bulbs from them. Yes, several times the cost but the company has quality products, has excellent customer support and won't melt your truck.

Hace tiempo las compre y aun siguen funcionando, son muy buenas

Look great and very bright!
