Can the LED's fit both ways in the socket?
When the bulbs are in the sockets they function correctly *when headlights are switched off*. When I turn on the headlights the LED's light up, then when the brake is depressed they light up brighter. The problem is that the third brake light comes on when the headlights are turned on, and it flashes brighter as well when the brakes are depressed. The bulbs go into the socket exactly like the filament bulb, they seat in by being pushed in and turned clockwise.
