1. A detailed description of the issue. Please include any error codes here.
On the Mercedes and Force India when using cockpit the on-screen wheel dash leds light a single light on the right to indicate DRS available and becomes two when DRS is active.
This is working OK in TT and Multiplayer but not in GP (no lights are shown).
