An LED is a type of diode, one that emits light. a diode in general is a "one way check valve" for electricity. this is why LEDs are polarity biased and they have a + and - side. if you run two lines of power both to the + side of the LED theres nothing to keep your system from feeding back into itself.
actually, you need them because you have two signals going to the same bulbs. if you have 8 volts going to an LED for the tail light, and then you run 11 volts to the same LED for the brake light, that 11 volts will feed back into the tail light wire (which is no big deal, its already on), but your problem arises when the opposite happens. because those wires are connected at the LED (brake and tail power wires), when the tail lights are on, the brake lights get some feedback.

Man I'm glad I have an electrician as a fried to help me wire this crap!

I thought the third brake light was simply +V and ground with +V switched and didn't think of how it was wired in with the rest of the system. Makes sense now!

1) yes all the LEDs in the tail lights are round top, the front turn signals are flat top
2) for the front turn signals i used orange, rear turn signals i used white, rear brake lights i used red
3) 5000MCD on front turns, 15000MCD on rear turns, 15000MCD on rear brakes.
i would recommend as high as possible. i only got 5000mcd for the flat LEDs because only 1 or 2 sellers on ebay offers them.

its actually the opposite. red light flows through a red lens way more than white light would. im redoing everything anyways in superflux LEDs. The tail lights were not as bright as i wanted so im doing everything superflux LED again. i wont be posting up until its all done again.

and you should use amber led's for your rear turn signal too.

he's right, think of it like this: a white light emits all colors of the spectrum and the red lense filters out everything except red. red LED's emit red and very little is filtered out, meaning the full 15000 mcd is making it through the lense.
and you should use amber led's for your rear turn signal too.
