Passenger headlamp started going on and off. Now it's fully off all the time. It's the whole assembly. Anyone have any experience with this? It's a 2011 cxl2 with hid's.

It isn't just one bulb. It's all of them on one headlamp
Have you checked the fuses under the hood. I believe that there is a fuse for each headlight assembly in the fuse box.

Check the main harness connection from the assembly to the wiring harness. Look for cracks in the harness and corrosion in the connection, first guess on troubleshooting. If you have a meter while apart check if it's getting power from the harness if the above doesn't appear to be the problem.

I replaced main bulb and ballast. All seems fine now. Assuming there's a safety that shuts headlamp off when one of these is faulty. Thanks for the great advice everyone.
