Couldn't find any reviews of these china xenon lights, so I thought I should make a short one. Bought three H4-3 35W 6000K xenon kits from Alibaba Aliexpress.com, from seller ATN Guangzhou Auto Parts Co.,Ltd Link to H4-3 xenon seller
The xenon kit is manufactured by Universal God Group ltd. / Guangzhou Shengda Electronic Co. ltd in China.
The package:
The box that arrived was a bit odd shape. It was externally in good condition, but the condition on the inside is a different story.
The sight when the package was opened. Xenon lights were not put in their packages. The packages are stacked at the bottom, and the xenon light trays are stacked on top of each other. The xenon trays are damaged and torn at edges.
One more picture with the top xenon tray removed.
Picture of the xenon light manual. It has been sitting between the xenon trays and one of the light metal frames has rubbed a hole through it. There were 3 xenon kits, but only 2 manuals.
Picture of one of the package. It is warped, moisture?
Close-up picture of one corner.
Light pattern:
Picture of the original H4 Halogen low beam light pattern. The light pattern looks just like it should be. A definite edge between light and dark, and there is no scatter. The pattern is asymmetric as rises to the right to get better visibility of the side of the road, and stays flat to the left so the light will not disturb oncoming traffic.
Picture with H4-3 6000k xenon kit installed in one headlight. The pattern is not asymmetric anymore and there is not a definite edge between light and dark. There are much light scattered around that will disturb oncoming traffic. The change in light pattern makes it easy to spot that it's an after market xenon, for those few that use these kits on the road, this will matter as the police seem to have been paying attention to the legality of these lights lately. The pattern scatters light so that when you are straight behind someone, the light hits their mirror. I've driven a couple times in front of lights like this, and it isn't pleasant.
Both lights in same picture. Green line added to see what the pattern should look like.
In the pictures you can see the difference in light power. Both pictures were taken with same setting on Canon EOS 400D. 1/100, f11 and 1600 ISO.
High beam pattern is good as you'd expect. When the light switches from high to low, the light pattern looks like it turns upside down. The light power is good, but the faulty low beam make them useless on the street.
Hi/Lo Mechanism:
A picture of the light in High and low position. The light moves forward and backward in the housing. The movement is barely visible in the picture, you will have to look closely comparing the two pictures to each other, it's only 5mm. It doesn't only change position, but also angle. By modifying the opening in the chromed protective steel housing, I'm sure you could get the light pattern better by bending the housing a bit.
