My car keeps showing that I have a light out but I don't. How do I reset this? Not a show stopper, just annoying.

 

Check your license plate bulbs.

 

as far as I know there is no reset, I know when I had it when I found the bulb in the taillight that was bad and replaced it the light automatically went out on the dash

 

To reset the 'bulb out' indicator you find and replace the broken bulb. But in my case I cannot find what causes the 'bulb out' light to come on and then go out.

My car has daytime running lights that are on all the time the car is in gear and the light comes on for a couple of seconds when I park and take it out of gear. Probably a glitch in the system when it senses a whole bunch of power is missing from the sensing circuit, the low beams and anything else that goes off.

Has anyone found out if there is a 'bulb out' indicator in the case of a broken 'bulb out' indicator bulb?

 

I have found that this is the one that most people miss, there is 2 of them. Hard to see especially if you are checking in the daylight.

 

Please note the owners' manual makes no reference to license plate bulbs being part of the light out indicator check. It specifically calls out headlights, tail lights, brake lights and side markers.

 

It may not say it, but they are, from personal experiance.

 

Take one of them out and I can assure you that you will get the light.

 

If its anything like a Volvo I had this device can be quite sensitive. When I replaced an out taillight bulb the indicator did not go out. I had to replace both tail light bulbs. Could also be a corroded socket or connection, ground etc.

I don't know how the MB checks bulbs but Volvo was comparing the current draw of bulbs in pairs- 2 headlights, 2 taillights, and on.

 

The OP (newbie) has not answered for two weeks, did not post pics as he said he would in another thread, why bother?

 

there might be other lights out 180...lol...

 

It was the right side marker. Thanks everyone

 

Stall me out 180. Non stop rain, college graduation in a week and I coach youth soccer. I haven't been able to wash yet. Come on man

 

This thread looks a little old but I would still like to say that in my experience
the "light out" light would come on as well and the problem was also the passenger side front marker (Orange) If your light out light comes on and you don't detect any obvious bulbs blown head light. tail light etc then 99% of time it means that one of the bulbs on the side markers is about to die and it is barely making it so that's why the computer detects it as a "light out" I replaced the bulb on both of my front markers and never had the problem again.

 

It happened to me as well when I first got the car and right before the safety inspection. I tried to find the problem, even at night with no luck. Took it in for the inspection and the guy told me it was the license plate. Best $5 I've spent.

 

My left license plate bulb socked in intermittent and I keep getting the damn light.




NOW, should I say it?
Why not?

If you are gonna rely totally on the manual, (even the SERVICE MANUAL) - you are gonna be a bit confused at times.

 

License Plate lights for sure. I put some LED's in there and they looked great, but set the "Light Out" indicator.
