I keep telling my wife and myself that! I have had repeated problems with dim light in my harley softtail tail light. It is a tombstone lens made of glass, and I have to run super bright bulbs, but on long trips tha vibration takes out the filament. I tried a really expensive LED replacement bulb, but it was so dim you couldn't see the brake lights during the daylight. I wish I was smart enough to invent the tail light bulb!Steve.
