The 10K potentiometer will allow you to adjust the point that the light comes on.   The capacitor is a 10 microfarad capacitor.  It's purpose is to keep the light from coming on when you turn and the level goes low for a second.  You can up the cap if it gives you too many falses while turning or stopping.  The cap needs to be at least 16 volts.  When I say up the cap, try a 22 mic  or a 33 microfarad.
