Great fit! Super bright! Awesome color!

Ziggy R. (United States)
Vehicle's information: 2021 Nissan Sentra S model. Sedan
Great lights! And bright!

These lights are awesome!
They look great, easy to install, and very bright.
I got the ice blue interior T-10 bulbs. The original ones I got that they would fit my car ( the LED festoon DE3022) do not fit a 2021 Nissan Sentra S, but after pulling the ones I need and cross referencing them I knew I needed the T-10 bulbs.
Over all I will definitely order more lights from Alla Lighting.
They seem well built, and I would imagine they would last a long time. ( will try and update or post a new review if they do not).

Also excellent shipping times! That’s a huge plus!

Thanks for a great product Alla!
