-

I put on my nissan altima 2008 , the blinking thing is not working just the light is on

They work very well and provide bright light.Easy to install and exactly as described.Recommended.

As advertised this product is considerably brighter than stock bulbs. There are a few minor things of note. * the dash warning on my 2020 Tahoe says there is a tail light malfunction when signaling. When signaling, the bulb flashes (strobes) twice as fast as the stock. However after 3 flashes, the error message comes on, and the speed of the flashes doubles. * when using the brake, it operates as advertised. (3 flashes then steady) *when using Hazzard lights It strobes twice per flash , compared to stock. Without any issues or dash warning.

Very nice lights, they fit great and were easy to install. Installed in my sisters Honda CRV. Super bright lights and she loves the strobe flashing as they turn on. Great way to get people's attention.

Bulb is really bright but didn’t even last for two months and already defective/broken. Light bulb just continues strobe and no more solid light after.

I installed these bulbs into non-OEM taillights. They replaced the original incandescent bulbs in my 2018 Toyota Tundra. They plug into the original sockets. When you shift into reverse, they flash three times and then stay bright. I guess the idea is to warn people you are about to back up. The bulbs seem to flash in sync. They seem very bright and white. There are LED patches all over the bulbs and a focusing lens that creates a beam effect to the rear. So you get a short range glow and kind of a beam. So far, they cause no malfunctions in the cruise control and such. (I just installed replacement tail lights that broke the on board computer and needed add on resistors to function properly). But, well, the first time I tried to remove the OEM tail lights, I broke them because I could not get one of the locator pins off and the tail light could not be reinstalled. This didn't matter to me since I was replacing the entire tail light assembly. But if you are just replacing a bulb, it might matter to you. So be careful with the assemblies.
