they work as they should and also they are bright, i recommend 100%

These lights are so bright they help me see at night perfectly the strobe affect is a nice touch.

First set didn't work, messaged company whom sent me an updated replacement without question. The replacements work perfectly! 100% plug and play. The bulbs strobe evenly and are solid and bright after strobing until the brake is released. I would recommend these to anyone and everyone.

I buy these brake light bulbs for every single vehicle I purchase / already have. They work great, it strobes correctly and they are very bright. They fit just like the standard halogen ones do. They look good, definitely gets peoples attention when I’m stopping. Overall it’s a great product and I’d recommend it, I haven’t seen any other strobing brake lights like this on Amazon.

Initially I was very impressed with these lights, they were bright and definitely drew attention when braking. however after just over 6 months of these being installed I've already had 1 bulb fail to work entirely.

Bought in January 2023, one bulb died in 11 months, love the lights.Only downside is they fit a little loose in my sockets, and unless I use something to help hold them in they eventually pop out.That and I figured LED's would last a little longer.Most of my other Alla lights have done pretty well.

I ordered Alla Lighting 3156 3157 LED Strobe Brake Lights Bulbs Super Bright and received it within a couple days. Initially ordered wrong type bulb housing so I suggest taking a look at the connectors of the bulbs already in vehicle first then pay attention the the type connectors before purchasing since there are multiple connector types.Installed just as easy as the OEM bulbs. Only have installed 2 days: drove to a few destinations to check any different responses from the vehicles behind me and to my surprise most started breaking further back than when OEM bulbs installed. They are bright, flash 3 times than remain on.Good item for the price, excellent packaging, delivered as expected. Highly recommended.

I bought this for my GMC terrain and was very disappointed at first due to the hyper flashing and the brake lights pulsating when you hold the brake lights (note I know they are supposed to blink several times before being solid and I am saying they are pulsating when holding brakes down). For most cars, you are going to have 2 routes one being the LED flasher relay which prevents hyper-flashing, or getting an Anti-FlickerResistor Kit. I learned my GMC Terrain does not have a flasher relay so I went to the Flicker Resistor Route that you can buy online on amazon for another 20 dollars. After this, the lights work like a charm.
