Im in the process of changing all the interior lamps to led,s but I seem to have hit a snag. I've managed to cannabilise the twist lock bulbs in the front interior light cluster by pulling out the W5W bulb and pushing in a wedge LED. The map reading lamps work ok, but the two courtesy lights don't. One still glows very dim when the doors are closed, and the other won't work at all. I've swapped them round and can confirm both are serviceable. The LEDs I'm using are non canbus, do I need canbus ones even though the interior lamps are not monitored by the bulb failure circuit?
