Hi all. I put some LED lights into the parking/sidelights. I got 3 working, but cannot get the left most nearside one to work. Every now and then if I wiggle it about, or switch off/on ignition I can get it to work, but the slightest movement and its off again. I've tried swapping the bulbs around to make sure it's not a duff bulb, the original bulb still works, so it's not the wiring; is there a knack to this? Attached an image of the type I'm using.
