I need to know the number for an amber rear turn signal bulbs for a 1990 300E.

I have clear signals so I need the amber bulbs.

Does anyone know the bulb number for Osram Sylvania?

I know the front ones are 1157A but I need the rear ones. Thanks, I don't have time to go to MB and the parts store didnt have my car listed.

You need a Osram/Sylvania 7506 21W. I'm not sure they come in amber.
Anything else will trigger the dash light out warning light.
