I replaced quite a few of my dash lamps with LED's and found quite a few of them annoyingly bright at night - such as the high beam indicator.
I ended up swapping them around so that only warning lights were LEDs and the lamps that would be on normally or for brief instances (indicators) were LEDs.
I never changed the general background illumination globes though as they would be too too bright and no dimming control if I tried to compensate.
Interior lights I'll try with LED's when/if the filament globes ever go. Don't mind the brightness for getting in/out of the car.
I also have LED's for the headlight park globes because I like the little blue glow - kind of cool.
I changed the centre brake strip of lights to high brightness Red LED's as half the globes were blown and its not a job to change them on a regular basis I'd like to do - works well.
Haven't gone down the route of park, indicator or stop globes though - too expensive and will probably give problems with the Light Module indicating faulty globes anyway.
