As I indicated above, it only comes on with either parking or head lights. If I remove the license plate bulbs, all the other outside lights work fine and no indicator light. The replacement bulbs appear to be identical to the original, but I guess I can always run by the stealer and pick up a bulb to eliminate that as the cause. Regards, Jerry |

Is the boot (Trunk) light included in the fault indication? Is the fact that there is no fuse for the fog lights another condition that will indicate a fault?

Another Taillight problem with 97 E300, Need it fixed Immediately
I was ticketed for my rear tailight bulb being out. However when I looked to replace it in the upper bulb space it looked like the light bulb assembly was never installed in this space.There was a flat cover on it and it would not accept one of the bulb assembles that are usually used. I have enclosed a picture. Do all E300's the same? If not can anyone clue me in on this phenomenom? Thanks

I had a pesky light failure indicator for several weeks in my 560. It turned out that there were cracked solder joints inside the bulb monitor module. All I had to do was open it up and re-solder the joints.

I was getting bulb out indicator on the dash, and only after doing all the head scratching, and pulling connectors in pairs, cleaning up the fuses, AND replacing the bulb out module with a spare I had kicking around... clued in here and LICENSE plate lights DING! Replaced it and problem went away.
Until today. Now, I'm getting same symptom as original poster. As soon as the car is started (light switch position = OFF, car parked) I get the indicator bulb on the dash. No lights are supposed to be on, how is this possible? First thing that comes to mind is put the original bulb indicator module back in and see if it goes away. I'll do that tonight.

I re-read the thread... the OP says failure indicator comes on soon as starting the car... same as me.
Then says adjusting the metal bits in a rear light cluster solved it. But none of these lights are "on" when the car is started. Does this mean: 1. the bulb failure module "reads" some lights even before they are being used? Maybe ones in the rear (where a driver can't really see the problem while driving, as he could with, say a headlamp out.) 2. the bulb failure module remembers or "latches" the failure, after using the light and module notices an outage of an important bulb, say, a brake light bulb, and doesn't let you forget until the problem is resolved? At least one of these has to be true, and possibly both. If after starting the car and you haven't used any lights yet for the drive cycle, and you get a failure indicator. ...Right? Thanks!

I found this in a related thread:
Quote:
So Sixtoes says it latches, but only for brake lights. It sounds as if the latch would be cleared when the key goes off, and not re-latch until brake is used again. ... or detected intermittent... So does this mean it can detect even if the light is not used, all by "itself"? Maybe. And that supports the OP's post and my observation of when it comes on, and what fixed the OP's problem. This makes me want to check my brake lights, before suspecting and yanking the bulb failure module itself.
