Illuminated rear door sills

[Sodertalje]

Guys, I have installed illuminated front sills long ago, and had "problem" ever since, but never get to ask...
Everything works, BUT, during the night when foot lights and sills are dimmed, if I open doors, sills and foot lights just blinks and turns off permanently until I turn the car off and then on.
Anybody expiereincig that issue?

Yes, it is caused by the fact that the sills draw too much power for the lighting system. I solved it by disconnecting the lights under the seats for the rear passengers.
