Well, first of all, these are halogen bulbs (it says so on the box) and not xenon! The brightness of the lighting is slightly worse than branded halogen bulbs, they are just white instead of yellow. I bought them just to try them out, pure white light on the road, as I said before, they illuminate worse compared to the classic ones. I didn't have any problem with the dashboard and they worked immediately. Chinese product, so time will tell if they are worth it or not, for emergency or testing purposes they are okay.

I start with 3 stars because I wanted to switch to white ones and test them, the brightness is the same as the ones I had (h7 phillips), maybe a little lower, so no complaints for a Chinese product that costs about 1.6€ per piece.

Update: after driving in dark conditions, I noticed that they are generally hazy but no problem on the road. Maybe they tire you out on long trips. There are better ones on the market by 1000%, you get what you pay for. For their cost, they do the job, hazy, but they do it.

The rating concerns the brightness, which is unacceptable as compared to other products, as they do not illuminate even half as much. The color is very nice, described as white, but they hardly illuminate at all.
