## Customer Reviews

### ⭐⭐⭐⭐⭐ No dash lights on and no hyper flash.
*by P***K on 10 June 2024*

Just a nice upgrade from the old dim halogen bulbs. No hyper flash, left the Hazzard lights on for about 24minutes to see if it would happen once they got hot and it didn't so am sure it won't happen waiting at red lights lol. No dash warning. And they are fitted to a Vauxhall zafira c 15plate.

### ⭐⭐⭐⭐⭐ Insanely bright! Watch my video!
*by E***4 on 27 December 2022*

The media could not be loaded. As you can see in the comparison video, this is a VERY bright bulb. I can't comment on longevity, but the build quality of the bulb appears to be nice and robust from an external viewpoint. Fitment is great as they're a very similar size to a halogen T20 bulb and the design of the bass was spot on.Highly recommended for the price, the brightness is just something else.

### ⭐⭐⭐⭐⭐ Best LED indicators
*by F***A on 1 September 2025*

Great lights. The have a great function without giving any errors what so ever.
