If its on the short wall, you won't even know there are lights. If its on the long wall and the lights bother you, you can stick some white duct tape over them. It looks like the head of your bed will be mostly blocked by the short wall anyway.
If you really want, its not difficult to disassemble the HPWC and unplug the lights, or maybe someday(or already) Tesla has come up with a software option to disable them.
