HID lights wiggle/ light pattern

[juf]

Hey guys, I just installed some HID lights from Retrofit Source on my Silverado. I'm pretty happy with them and they're definitely brighter than stock. I've got two problems though. When my truck goes over a bump or rough road the lights seem to wiggle. It's not flickering, but the whole light pattern shakes briefly. Is this normal?

 

Also the light pattern is terrible. I know the stock projectors aren't the greatest thing in the world, but I've got a lot of shadows in my beam pattern. I didn't notice the light pattern with the stock lights, but maybe because they weren't bright enough.

 

Anyone got any ideas of how to fix these problems?

sounds like you don't have the bulb seated correctly. check that out, see if it helps

I'm pretty sure I got the bulb seated in all the way. I was thinking about that potential problem while installing. I'll definitely check it out though. I tried to get some pics of my light pattern tonight. Does it look normal? Notice the dark spot close to the middle and how the edges almost arc out?

The wiggle has actually seemed to go away some. Anyone know of turning the bulbs a different orientation might work? My bulbs had the one big tab and 2 small tabs. I aligned it up with the holes where the light goes, but maybe that's not the best orientation?
