These are a lot brighter than what I got at the parts store, but I do not know how well they work at night.

Did not specify there were two in each package and did not fit when we got it. Upside easily returned so thank you for that!

I have ordered Alla bulbs for 3 different fleet vehicles now, and its the brand I am sticking with. I prefer to change out flasher to prevent fast flash rather than the resistor which some offer, its from an electronics engineering background I base this decision. the performance is great I can see the difference when I step on the brakes from inside.

Replaced stock tail light/ brake light bulbs and love the Alla lights. Have used them for all bulb replacements on multiple vehicles and motorcycles.

I ordered these to replace regular bulbs that only lasted two weeks. They are bright and work well, except they blink faster than normal, about the same as when the blinker is burned out. Since these should last the remaining life of my vehicle, that probably is not much of an issue, but I just like the slower blink.

I had originally purchased a set of 4 tail light bulbs from Yorkim. Once I installed them they were far better than the old style bulb, but not much of a difference between running light and break light. Having experience with Alla and their astounding customer service I decided to order a set of break lights and try them out. There is a huge difference, the Alla lights are much brighter and a more richer red. They are much brighter than the Yorkim and a more focused light. 20 mins after I installed them in a 2002 Alero I was pulled over by the local police wanting to know what brand they were and where I got them. I am pretty sure the officer is going to buy or has already order a set. These bulbs are worth the money, I am not sure how long they will last but time will tell.

does what they are supposed to. definitely an upgrade over OEM tail light bulbs. Ive had brighter reverse lights on previous vehicles for close to the same price or cheaper, but hey, thats inflation i guess?

Old Review: READ THE UPDATE... buy without hesitation. These LED flashing brake strobe lights simply do not flash in a Ford Pickup Truck. They work just like incandescent 12 v bulbs. The turn signal blinks normally, the parking tail lights come on and high beams but the Brake DOES NOT strobe. Brake lights come on but no strobe. I bought these bulbs... THE NEW VERSION... expressly to get brake lights that flash several times and then go solid. This is crap. I tested the bulbs with other 12 volt sources and they dont strobe as advertised. Warranty is good for NOTHING! [Wrong statement this was not a warranty issue but a customer satisfaction issue... my regretable misuse of words] UPDATE IMPORTANT READ! ALLA comes through! Without provocation, ALLA Company approached me AFTER my Amazon return window had passed for the singular purpose of helping me achieve 100% satisfaction. I have never had this happen with an Amazon vendor... That is worth ten stars to me **********! Completely unexpected. They didnt even want me to change my review. Understand that I am a customer of ALLA and have bought two packages of strobe brake lamps for my Honda Element. I was rear-ended by a reckless texter driving a HUMMER H2. The Hummer leads the world in rear-end fatalities so we got smashed. My Element sustained lots of damage and I too was hurt in the wreck. Honda Elements are tough. Nevertheless, it took me nearly a year to complete the body work and repairs on the Element and I have some photos. I wanted to find a solution to try to never get hit in a rear-end collision again. That is why I want all my vehicles to have strobe brake lights. The Honda Elements ALLA brake lights are perfect so I did not need customer service. But the new lights for my big Ford 350 did not strobe and I was outside the Amazon return window. The bulbs worked just like the old bulbs so I was no worse off but I wanted those strobes. Well, it wasnt to be. ALLA offered to let me try a different bulb with new technology or a full refund. Turns out flashers dont work in all vehicles and all years. I didnt want the company paying postage and all that if the new bulbs were unknown to work. But I would say that this is the best customer service I have ever encountered on Amazon. They showed no hesitation to fix this. They didnt want me to change my review. This wasnt a warranty issue. The bulbs work great. This was a customer satisfaction issue. I have added some pictures of my Honda. One is the rear quarter that was blasted in and it is after the first frame pull. Then you will see the finished quarter wheel well result and my Honda Element, the most beautiful in all the world. With ALLA flashing strobe brake lights. Sometimes you cant get anything to work out in this world. But sometimes you turn disaster into art. This company ALLA went way out of its way to seek my satisfaction. Little did they know that their strobe brake lights are an important safety provision on the most beautiful Honda Element in the world. This Honda saved my life; I saved its life. I hope you never suffer a hit as I took from a texting moron driving a Hummer for the first time. I was stopped at a red light on a clear day, and they clobbered us. I have more cars and I will buy strobe brakes for all of them ... from my friends at ALLA. If your bulbs dont work in your car, let them know and they will take it from there.

They are nice and bright last long time and over all have a great look to.

After insalling, the blinkers blink super fast. My 06 silverado needs an additional resistor because they take so little energy to run, ( WHICH IS GOOD, RIGHT?) that it registers as a nonfunctioning light. So I need to wire in a resistor somewhere I guess.. Would be awesome if that resistor could be incorporated in to the light. But THEY LOOK COOL and finish the full LED change over. My sea light headlights work without issue.
