I installed the Syneticusa 1157 LED bulbs on my car, and the yellow light is super bright! No hyper flash either, which is a plus. I’m really happy with how they look as turn signals and daytime running lights.

Disappointed with the color
I was really looking forward to the yellow amber look, but the color seems off compared to what I expected. They work fine, just not as vibrant as I'd hoped. Also took a while to arrive.

Good but with a minor issue
These Syneticusa bulbs are great in terms of brightness, but one of them flickered a bit during install. I checked the connections, and it seems fine now. Just a little annoying to deal with it at first.
