Pack-2 Car H7 LED Fog Light, Shockproof Integrated Metal Lamp Body Fast Heat Dissipation 50000H Bulb, Plug and Play Quick Start Bulb with Focusing Lens, Universal for Most Cars (White)

These are quite bright when they are working, since installing them, they work most of the time, but sometimes when I hit a bump, they flicker on and off. They have been checked multiple times and are correctly seated into the socket.

I installed these in my 2011 Jetta, and while they worked (and didn't flicker like some LEDs), they just aren't that bright. I thought that with the front lens paired with the car's reflector, that they'd be super bright, but they're just not. I switched to some other LEDs that just have diodes on 2 sides (no lens/projector). and they're much more effective. These look cool, but I want them to light up the road!
