When did lightbulbs stop using universal design? Our lightbulb in the bathroom had burned out in the fan and I wanted to replace it only to find a stupid two-pin lightbulb. Thanks Revane, I never have to wait 2 days to turn my bathroom light back on because we have a supply of about 10 bulbs in the house. Now if it burns out, I can replace it quickly and without any problems. Seriously, who thought that was a good idea?
