## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect fit
*by D***. on May 20, 2024*

Blue led lights for my vintage vw worked beautifully nice and bright and a beautiful colour

### ⭐⭐⭐⭐⭐ Worked great
*by D***R on February 27, 2025*

I bought these to replace the speedometer and fuel gauge lights on my vintage VW Beetle. These are the non-polarity ones, I needed these bulbs for the idiot lights and the turn signal indicator and they worked perfect. Just installed them, can’t speak to the bulb life. Included a couple pics of the fuel gauge, incandescent vs LED.

### ⭐⭐⭐⭐ Non dimming
*by M***B on August 1, 2024*

They work well, pretty bright which was what I wanted. They don't dim which may bother some buyers.
