The light in the OBC has gone, but it works since you see it if you glare at it up close. I took the OBC out of the dash, removed the bulb assembly from the side (white plastic thing), with 2 bulbs welded to it. I soldered two new 1.2W 12v bulbs, but no light. I was wondering if someone would know why this doesn't work. Is the wattage/volt different? do I need to buy the whole bulb assembly, or is there something else that I am missing.
