2002 Q45 (GF50) interior lights

[dormicum]

is there any control module for the interior lights of 2002 Q

i found that my Q's Rt rear room light is not function upon open the door and it keeps to remain as dim even the security system is ON while the others is OFF automatically

I would check that door's switch before looking further.

thanks in advance

the door switch seems OKas the step light would go OFF when the door closed

i got the symptom just after i changed the room lamps to LEDs

i am afraid some fuse may broken by me

[maxnix]

Do the LED assemblies have the same resistance of each bulb it replaces?

[dormicum]

probably yes

but if no, what is the consequence????????

If you have dimming lights which the f50 does you can't dim Led's. So just put back th old bulbs. the lights are controlled by the BCM and you don't want to break that.

LEDs are dimmable by pulsing the current high and low. It then appears as PWM. Need a separate controller to achieve this functionality.

But in our F50 it's not configurable as BCM has limits. The current draw for LEDs are at least 20mA and incandescent (depends what size) could be as high as 200mA. Probably you bought the wrong LED replacement.

SoWhere is the BCM

If you have dimming lights which the f50 does you can't dim Led's. So just put back th old bulbs. the lights are controlled by the BCM and you don't want to break that.

actuallyThe left side functioned normally, just like tradition bulbBut the left side went wrong
