re: sequential lights: Ours would look most like the mustang ones, if you red out the turn signal. the simple "fade into brake" pattern, and "sequential turn" signals should be perfectly legal.. you don't have any high speed blinking, strobe, or etc that typically gets the cops attention.. in fact the only problem might be the redded out turn signal ins ome states.. but the carw as offered that way stock, (m edition) so i doubt it would be an actual issue.
King, i think this would look particularly good with my set, given the red out look... have you decided what you're doing with yours yet? keeping them as above, without the clears?
btw you don't need LED's to do the sequential thing.. just a controller. After looking at various versions, i even think for the basic operation (ie: sequential turn signal, and fading into brake lights) that standard bulbs will look better because they have a short interval of brightening and dimming, aiding in the transition effect, whereas led's are instant on/off. If you want the strobe effect, and fast blinking, then you'd mneed LEDs.
*edit here's a link to a circuit to control LEDs

I'm still looking for a DIY incandescent circuit however.
