Alla Lighting Red LED Bulbs 3156 3157 - 3000lm, Ideal for Turn Signal, Stop Brake, and Tail Lights - T25 3047 3057 3457 4157 4057 3155 - Suitable for Cars, Trucks, Motorcycles - Extreme Super Brightness Review

Installed on my 2018 F150. No hyper flashes outside (because you have to forscan in the cockpit), no flickering. I trust Alla's lighting, since I've had a 4Runner it has never let me down. For this particular bulb, the bulb is very solid, feels solid in the hand, the radiation pattern is very similar to halogen, but who cares, it's a brake light anyway.

One of Alla's lamps stopped working after just a few months (with minimal driving during the pandemic). It will no longer burn high for the brake. I expect an intermittent LED bulb to last longer. I find that this short lifespan is common to all these super bright Chinese LED bulbs. Looking for something more reliable.

These bulbs are very bright but some bulbs may be broken. I bought a pair on April 18th and on May 14th I was told that one of my brake lights was not working. Did a test to make sure it wasn't my outlet and then sniffed. He's definitely burned out. I didn't jump on the car at all and I had no electrical problems. Must have just hit or missed.

Easy to install, crisp and clear compared to stock bulbs. I bought these for my 2015 Jeep Wrangler, please note you need a pull up resistor to prevent hyper flash for the turn signal. I also have reversing LEDs and they don't require a load resistor but are just as bright and clear which gives you the option of keeping the factory taillight housing but increasing the light output and increasing their replacement time.

One of the few lamps that works perfectly as a rear brake replacement. A beautiful red glow day and night, and the brake function is noticeably brighter day and night. They do not heat up your body's lens and do not tarnish when heated. What you see when you plug them in is what they will be after 2 hours of driving. Oh, and the taillight feature doesn't make you look like a jackass with your foot on the brake. (We've all seen those overly bright taillights)

Didn't last more than a month. Bought March 31st, received April 2nd, removed May 30th, had to be replaced May 31st. They were bright and I really liked them, but I've only had them for a month and they were out of service. I was pulled over by the police late at night, luckily it was only a warning but being stopped for lights is quite embarrassing. I checked the wiring with a volt meter and there was no problem so I figured it was the lights. I replaced them. The Sylvania LEDs aren't that…

Many years ago I bought a set of LED bulbs to replace the incandescent bulbs on my 2003 Silverado. At that time they were the most modern and as bright as possible. These Alla just fuck with their brightness. Also, each of the old LED lamps consists of 13 individual LEDs, which is three times the size of the six LEDs in Alla lamps, which shows how far the technology has come. I used to think of simply replacing the stock taillights with a pair of LED taillights, but with these bulbs that would…

They're pretty bright in my 2014 Jeep Grand Cherokee so this part was good. However yesterday when I was driving to work a police officer pulled up next to me at a traffic light and when I rolled down the window he told me that only my 3rd center brake light is working and will need to be fixed soon. lanes or braked to turn, drivers behind me were not warned. And because I had to painstakingly install terminators in the bulbs to prevent excessive flickering when the bulbs burned out, I didn't…
