Installed HID headlamps and LED driving lights, battery indicator lamp came on today

[chris97boxster]

Been running HID kit for a whole year
no issues.
BUT remember stock halogens run @ 55Watt
the HID's run @ 35 Watt.
HID's draw less power after they ignite

the H7 kit is PNP (plug and Play)
It doesn't require any extra splicing/grounding

Loose ground somewhere else?
maybe a wire came loose?
re-check connections that you touched
tape them if necessary
make sure all added components are secure/zip tied

check alternator output and or the battery(how old is it?)
Good luck
Chris
