Dome lights dimming after a few minutes

Hi - I have done a full LED replace for all interior lights. I've noticed that if I sit with the doors closed and car off, the lights dim after a few minutes. I never tried this before the LED replacements. I am assuming there is a relay somewhere that cuts voltage after a period of time. I'd like to bypass that relay. Anyone know what it might be?

Thanks!

Have you manually turned the interior lights on, or when interior normally come one such as opening/closing door or turning engine off?


I have updated all interior to LED, and not noticed any change in behavior over the original bulbs.
