Only the very brightest LED's would really equal the brightness of the bulbs. Generally, they are very directional, although you can buy them with different light cones. I have, however, experimentally replaced the red,yellow, and green lights along the bottom of my console with LED's (super-bright and very concentrated types). For this application, having a narrow cone of light is actually a good thing. This helps, because I can't see the turn signals with the top down on my car (A common complaint, can't hear 'em either) and I don't want to look like the other idiots making a left turn around the world.
You're right, LED's can't be "dimmed" in the conventional sense, but they could be modulated with a duty cycle ranging from 5% to 100% at a fairly high frequency, giving the illusion of dimming. The regulator, voltage/duty cycle converter and switch could be built into the base of a replacement bulb. But nobody's done this...yet...hehe...you read it here first.
