Assuming you did get the right dimensions of your Dome lamp bulb and replaced it with the "festoon" LED bulb, I'd be curious to know if these "Festoon" LED bulbs are dimmer (or brighter) than the stock bulb as so many LED's turn out to be dimmer in my experience. They look cool and look like they'd crank out some serious light, but everytime I trade out stock bulbs for LED replacements its always turns out to be a disappointment in terms of comparable light output. If you want accent lighting, however, they're good for that. Has anyone tried a "Festoon" white LED bulb in their domelamp? Thanks
