Fast flashing turn signals and hazard lights
 

Recently on my 380sl I have noticed that the turn signals are very rapid and also when I turn on the hazard switch all the lights back and front are flashing very fast. I checked all the bulbs in the trunk on both sides and the front turn signal bulbs and they appear fine. Could the problem be the hazard relay or turn signal relay. Any help from a tech out there would really help.

Looks like on of lamp on the line went off, or incorrect voltage.
Use to have same problem on 1994 Skoda - was funny to find it is created by.. rear license plate illumination lamp
