Atomic, that LEDtronics site looks best,, they have LED's that not only point backards but also are faced sideways to compensate for the all around glow of a incandesent bulb. And if it is what i think it is, they will be much brighter than an incandesent. Not only that but if you were to get red LED's for your tail lights and amber lights for your turn signals, i would imagine it would give a much better glow and color richness, and in turn update the outside of the car.
