Help! rear right red lamp doesn't work

Hi everyone,

Hmmm...! Ok, maybe it's the fog light. I do not drive with it all the time but when I do use it I notice that and thought it was wiered. So, it is supposed to be like that, any reason why?

IT IS THE FOG LIGHT!

Otherwise known as the courtesy fog lamp, which are found in many european cars (All my volvos have them). They are not standard for american nor japanese cars. These are turned on to alert the vehicles driving behind you of your presence during foggy conditions. Sometimes your rear running lights (red) are not bright enough for the drivers to see you in foggy conditions so it is necessary for a brighter red light. It is only on the left side because two bright red lights on the left and right would look like you are stepping on your brakes.

That is exactly why you cannot turn this lamp on without turning the front fog lamps on first. It follows the logical sequence of fog alert.

1) See fog in front = turn on front fog lamps by pulling light switch first time.
2) Fog too thick, danger of getting hit from behind = turn on rear courtesy light by pulling light switch second time.

I certainly hope that you do not drive using it at all unless necessary. Those who turn on this courtesy lamp on without the presence of fog would look errmm, uummm ... kinda stup.d, in my opinion.

the purpose of the rear for light is so people behind you can see you when it's foggy out. making it a dual set-up would confuse a lot of people into thinking they're brake lights.

Thank you Pasfo for the detailed explanation. I had a e320 1994 and had the same thing but was always curious why. I'm glad I asked this question now I'll be able to explain someone why it is that way. I have been to the forum since last week and I have learned so much about my car and MB in general already.

I guess now I have to work on my bad habit of turning hd light switch and pulling all the way activating both front and rear fog lights. Thanks!

By "great book," you mean the owner's manual, which describes this feature? <g,d,r>

True, yet "great book" is the last thing we look at.
