## Customer Reviews

### ⭐⭐⭐⭐⭐ Bright and beautiful, Switch backs look great
*by U***C on April 12, 2021*

After 4-6 months the bulbs start to burn out a couple of bulb panels and continue till over half don't illuminate.

### ⭐⭐⭐⭐⭐ Great bulbs and great service
*by R***B on June 8, 2025*

They look amazing and customer service is great.

### ⭐ burnt out within a few months....while sitting in Storage.
*by L***L on April 25, 2025*

I bought these last March 2024 and it is now April 2025. I have had my car in Storage all Winter Since it is a Corvette and I live in WI. I took my car out of Storage about a week ago and one of the lights I bought is already burnt out. It has a one year warranty but since my car has been in Storage....I actually only used the lights for a few months last year and since by date and not by use the warranty s up...I would suggest avoiding this product. It should have lasted way longer than that.
