Indicator light?
 

I have a 1975 450sl, on the instrument cluster between high beam indicator and tripometer reset button is a indicator symbol shaped like dot with a circle around it. Can someone tell me what this is for.

Thanks

Does it look like any of these?

how about this?

(sorry about the glare)
I think the earlier SL's had a different gague cluster, because I don't have the fuel economy gague like yours, and there are a few other differences. this is off a 78 450 SL

Maybe?
 

Sounds like this could be the disk brake pad wear indicator. Just a thought.

Hi

The 78 450sl picture is very close to my dashboard arrangement.
Where yours say's brake that is the location of my symbol.

Thanks

look at the next symbol to the right... it looks like a circle with some dashes around it... if you're talking aobut that, it's the brake pad wear indicator. Hope this helps.
