Nick, I cannot speak for the others but the silver bulbs I had on the Mustang were as bright as the standard amber bulbs but, IMHO, improved the look over the stock 'fried egg' look. Personally, I am not to bothered about the amber lights on the Morgan, although I do think certain body colours look cleaner with white lights, rather than amber. It is purely a style choice and as long as the candle power isn't decreased, or the function of the bulb, I cannot see an issue.
