4PCS 3157 LED Bulb Brake Tail Light 12V-24V Super Bright 3156 3056 3057 3047 4157 LED Replacement Light Kit Set for Car Tail Brake Lights - Brilliant Red

I recently installed the iFunyLED 3157 LED bulbs in my 2016 Ford Focus, and I’m extremely impressed. The bulbs fit perfectly into the 3057/3357/3457/4157 sockets with no modifications needed, making installation quick and hassle-free. The brightness is phenomenal—way better than my old halogen bulbs. Night driving has become much safer because I can clearly see the road and other vehicles without straining my eyes. The LED light is crisp and clean, giving my Focus a modern, upgraded look. I also appreciate that the kit comes with multiple bulbs, so you can upgrade all your lights at once if needed. No flickering, no error messages—everything works perfectly. If you’re looking for a reliable, bright, and easy-to-install LED upgrade for your Focus, these iFunyLED bulbs are a fantastic choice. Highly recommend!

Wow, these are so bright Im still seeing spots after doing my post installation tests. I mean, there's no comparison to the other LED signal bulbs Ive tried in the past...I hope these last because they're amazingly bright! Well worth the money.

worked great, we have a working tail light now! took the computer a minute to recognize it was changed (it makes a different blinker tick when the bulb is dead or dying) but after a day it was reset and good to go.

So far they're working, as in they provide illumination. I don't think they are "Super Bright". They seem to be about the same as incandescent bulbs. The other thing I'm noticing on day 1, is that its throwing off the PCM making it think there is a burnt out bulb. The "fast blinker" is an indication that a bulb is burnt out, and its doing that for both the right and left. However it doesn't do it every time, which is strange. That may be more of a "me" problem with a 2010 model. The 4 stars are because of the illumination strength not lining up with the description. They were inexpensive, and simple to install. I have no idea how long they'll last yet and if the "fast blinker" is going to annoy me. Update: I ended up disabling the "Rear Turn Lamp Outage Detection" in the vehicles Smart Junction Box settings.

Lights are bright but for well work with no issue. Be aware that they may cause "hyper flash"

If you’re tired of the person behind you using your back bumper as a landmark, this is the light for you! I installed this LED brake light, and now I’m convinced the car behind me is actually a safe distance away for the first time in weeks. It's so bright, I think I inadvertently signaled the International Space Station when I hit the brakes at a red light last night. The guy in the pickup truck behind me actually shielded his eyes and blinked three times to signal 'roger that'. The installation was a breeze – just plug and pray you don't blind anyone permanently. It fit perfectly, unlike my New Year’s resolutions. Five stars! My braking has never felt so self-important and visible.

No flickering, works good. Does make the blinkers blink faster, so probably need at resistor.

Even though this bulb fits the socket and will illuminate as described. It will not operate properly in a 2002 Dodge ram 1500 pickup truck. It continually shows on the dash that the bulb is out. The flashers for the turn signals are erratic. I plan on keeping these bulbs for the backup lights but we'll be returning one of the 2 packages purchased. If your vehicle has a double filament bulb, this is not a good replacement.

These lights are very nice for a month, then they start burning out and flickering. Nor impressed with them only working for a month.

buena iluminación, y hay que conocer dentro de los led y estar actualizados para saber que estos son calidad premium.
