The effect is pure madness, I decided for this product due to the super reviews. I once tried the effect with photographs to document (on which one sees an image that GEEEEELBE parking light compared to the very white H7 bulbs).
Advantages for me:
- Exterm bright and especially "strong" light
- Xenon optics !!!
- Price !!! 50% cheaper than the Philips
For life I can not say anything yet, but follow.
