LASFIT 7443 7440 LED Bulbs Reverse Backup Light, 7444 7444na White T20 Daytime Running DRL Parking Lamp L-7440 W21W WY21W 6000K for Automotive Replacement, Plug and Play, Pack of 2

Purchased these for the reverse lights on my 2020 Toyota 4runner. Very easy to instal and the fitment was great. They are so much brighter than the stock bulbs. Happy with the look.

Absolutely the best Amazon LED tail lights for a 2023-2025 F-250 to replace the incandescent bulbs. Simple 5-10 minute replacement, and work 1st time without installing resistors. I had 1 light OEM light bulb go out (turn signal started flashing like a spastic) so I replaced all 4 with these LED’s. They work great. Got the red because of the YouTube reviews and bright and instant-on.

In my car they are used as drl and high beam. Installation was tight but simple. I appreciated the included gloves, so I never had to touch the bulbs. Great difference to halogen lights. Very bright, but not blue. And of course they shine very stable, no flicker or vibration. All in all: great product for a great price.

Works great with any 3157 bulb! It says it wasn’t compatible with my F150 but it works great! Does require a resistor to prevent hyper flashing. Way brighter than OE bulbs and safer as well since higher visibility from behind. I swapped all the bulbs on my truck with this brand and they’ve all been great!

These are very bright, and they do include an internal resistor. Those benefits earn it 2 stars. Unfortunately, the internal resistors do not prevent them from hyperflashing entirely, so I believe that the resitor has too low of a value. What happens is this: it flashes normally for 20-30 seconds, and then begins hyper-flashing. When I turn on the turn signal, it flashes normally for a short while. If I use the lane-change setting for the turn signal that flashes 4 times and stops, all is fine. If I turn on the turn signal as I'm approaching an intersection, and I complete the turn right away, all is fine. If I pull up to a stop light and I'm sitting for 30+ seconds, the flashing becomes erratic - sometimes hyper-flash, sometimes not. The flashing is all over the place at this point. If I turn it off and then turn it right back on, it's still flashing erratically. If I turn it off for a few minutes, it goes back to normal for short uses.Since the hyper-flashing occurs on both the left and right signals, it tells me that it's a design flaw. I suggest trying a different manufacturer.EDIT:The manufacturer was very gracious and contacted me. I should note that I have used Lasfit LED lights elsewhere in my vehicles and the others function great. It's just the turn signals in my truck where they have a problem.2nd EDIT:It's very difficult to find this bulb in red, with a built-in resistor. In fact, it's the only one I could find. Since I still needed it, I left it installed and then added a second resistor to it. I added the Sylvania 27 watt (https://www.amazon.com/dp/B01A77U122 ) and have not had any problems since then. My advice is if you need a red T15/912, order this and see if the resistor is enough for your vehicle. If so, great! If not, you can add a resistor and it should work fine.

I loved it, super easy to install and no error codes for my F30 bmw and it is very bright!

Let me start by saying: LASFIT is one of those rare unicorn companies that actually cares if their stuff works. Shocking, I know. They refunded me for a pair of bulbs that should have worked but apparently my car had other plans — probably because it was built during a Mercury retrograde.These 7443 LED bulbs are advertised as “super bright,” and LASFIT isn’t kidding. I installed them, tapped the brakes, and I swear a nearby squirrel threw on sunglasses. Planes started circling. NASA might have logged my taillights as an unidentified celestial event. It’s everything I dreamed of and more.Of course, because life can’t be too easy, the first set I got decided that “lighting up” was a suggestion, not a job requirement. But again — LASFIT stepped in like a customer service superhero, issued a refund, and didn’t make me submit DNA samples or write a 500-word essay on why I deserved it.So if you’re in the market for blindingly effective lights that may or may not confuse your car’s fragile ego — this is the bulb for you. And if something goes sideways? LASFIT has your back faster than your car can throw a “bulb out” warning light.Would buy again. Will probably need to, because my car is clearly powered by petty spite and electrical mystery.

Very bright, they have a nice size to them, seem to be fairly well built and they plug into the socket very nicely with a firm click and they definitely are not vibrating loose. They are definitely yellow though not Amber, still has a nice color and makes you extremely visible but if you are looking for that deep rich amber, these ones are definitely more of a yellow shade.
