Dim taillight bulb issue

[eightynine535]

Hi all,

I have I think a unique issue with my taillight bulbs. I’ve already read up and re-grounded the lights as that was a separate issue.

The issue now are the main taillight bulbs being dim and throwing a code on the dash. The corner/brake lights and turn signals both work fine and are the correct brightness. I rechecked the grounds and they are fine. But when I supple positive from the battery to the bulb in question. It lights up as it should. Remove the wire and it goes back dim.

What gives??? Any suggestions?

What year? The LCM controls how much power is going to that bulb, as it should be a single filament type.

Oh and if you didn't know:

The recall is for model years 2002-2005 of the 325i, 325xi, 330i and 330xi cars, the Munich-based company said today in a posting on the National Highway Traffic Safety Administration's website.


Lights including tail, brake and turn signals may only work intermittently on the cars, BMW told the auto-safety regulator. This "reduces the ability to warn other motorists of the driver's intentions" and "could cause a vehicle to crash without warning," the company said.
