PHINLION 7443 7444 LED Turn Signal Light Bulb, 3600LM Super Bright 7440 7442 7443A 7444NA LED Directional Blinker Bulbs and Parking Lights for Cars, Trucks, SUVs, Amber Yellow

HIghly recommend these white LED bulbs, with a few "howevers..." that the user needs to understand.The single element on the top, under the projector lens is super bright - even for being one LED package. I would say the combination of the CSP 1860 LED element and the lens definitely makes for a more intense illumination point of light than compared to a tungsten filament bulb when viewing just the top of the bulb. This works especially well for turn signals and brake lights that need to have a high intensity beam of light "punch through" rain, fog, mist, etc and reach out as far ahead and behind the vehicle as possible. But perhaps not the best choice for backup lights - here, you need a wide flood beam pattern that only needs to reach back 20-30 feet.HOWEVER... this is not the end of the story! A well designed bulb mounting will have a reflector that surrounds the bulb and gathers all 360 degrees of light coming from the light-creating element and redirect it out in one direction. In order to do this, the light-creating element (be it the tungsten filament wire, or the LED element) must be positioned at the focal point of the reflector. If your car came from the factory with tungsten bulbs, then your reflectors may be designed to work best with only that exact bulb. In the case of my 2004 Acura TSX, the reflectors were designed very well to make the most out of the 7440/7443 bulbs. These Phinlion LED bulb are better than most in getting the LED elements closer to the socket... but, they are still not at the correct height to match a 7440 bulb (and thus, the focal point in the reflector). YMMV (your mileage may vary)... you will have to try these in your own particular vehicle side-by-side with LED on one side and stock bulbs on the other to see which work best. The brightest bulb may not always result in creating the most attention-getting effect to the car behind you.So, what am I saying? When viewing my tail lights, for example from 50' away (as if I was in another car behind me) I can tell that with the LED bulbs, that the reflector is not being used as effectively as the stock 7440/7443 bulbs. However, I felt that the superior intensity of these LED bulbs have enough "attention-grabbing power" to outweigh their less effective use of the reflector. Also, the high intensity projector beam out the top of the bulb should be visible behind me to a greater distance in the mist and rain.Because that is the bottom line, isn't it? In a sea of red tail lights on a rainy freeway, I want to wake up and get the attention of as many drivers as possible that I am braking or need to change lanes.As for the red LED bulbs, be aware that the red will never be as bright as the white. Regardless of the marketing and blanket product description that they are "3600 Lumens" (actually, 1800 lumens per bulb). In a product series like this, White will be brightest, next is Amber, and lower is Red (I think it is because of the phosphors used to make Amber and Red).If you have red or amber colored lenses on your vehicle, and you want the most lumens possible coming out your lights, then install the white bulbs. And here is the "However..." that comes with it. At the high intensity of these bulbs, a white LED bulb behind a red lens will have a tendency to slightly wash the color to pink. If you want a beautiful RED, put a red LED behind a red lens - you will have a more saturated red, but it will be less bright.Same for amber - these super bright whites will slightly wash the amber towards yellow. But, since amber LED still has about 90% of the lumen power as white, you could put the amber LED behind the amber lens and enjoy the richer amber color and probably not notice the slight difference in lumens.Now, here is an interesting science fact, boys and girls that I'm using for myself right now: You can put an amber LED behind a red lens and it works great! It is the compromise of choosing between red or white for a red lens. Amber LED's are way brighter than red, but only slightly less bright than white. And when an amber LED is placed behind a red lens, it keeps the red from washing out to pink. So, you still get a satisfying redish color at only a slight loss of lumen output.In the attached photo, the left is the stock bulb, and the right is the Phinlion red LED. The human eye is much better at seeing these things at night than a camera... so as they say, the camera does not do it justice. Keeping that in mind, on the left you can see that the reflector is well filled out - every facet in the reflector was precisely aimed to catch light from the tungsten filament and reflect it out the back of the lens. On the right side, there is a dead halo around the bulb - this is because the light-emitting elements of the LED bulb are not at the correct focal point of the reflector. In the case of this car, I decided that the significant gain of intensity of the LED over the stock bulb was enough to outweigh the decreased effectiveness of the reflector due to the LED elements not being at the correct focal point and chose to keep the LED's installed.ps, I have 4 of these Phinlion bulbs installed and do not notice any radio interference (am or fm).

It's very bright, and seems to be good quality, no issues so far. The color hue is perfect, it's very vivid. (Amber) it also isn't tall enough to touch my lens.

Is a great set of lights. One thing to know is you do get hyper flash when using them. Make sure you purchase load resistors so they blink normally. While there are bulbs on the market that do not require load resistors, they are also much more expensive. Doing a little wiring work to make them blink normally with the resistors is the way to go. There are youtube videos to show how this is done and how easy it is. Nice lights

Installed these brake light bulbs in hopes for brighter lights on my 2005 Toyota 4Runner but instead costed me more money than I should’ve spent. Had these for 5 months and suddenly last month, car had ABS light and VSC traction control light come on and decided to replace them with the old factory halogen bulbs because one was brighter than the other and what do you know, abs and traction control light turned off! If you’re scrolling through the reviews and come upon this review in particular, heed my warning, steer CLEAR AWAY from this brand. Go to LASFIT or something we’ll known brand. You will get your moneys worth with pricier bulbs or anything in that matter.

These latch in place loosely. After two weeks of install I noticed my right taillight was out. Took it apart and found out the bulb had fallen out of the socket inside the taillight assembly. I put it back and secured it with tape. Did the same thing for my left taillight which was almost out of the socket.

Easily installed and much brighter.

They are very well built lights. They are very bright and definitely make you stand out. In my vehicle, I did notice that if you put them in one way they work completely normal. However if you turn them and put them right back in they hyper flash. But turning them half a turn and putting them back in completely fixes that problem.
