I wanted to share the parts I used in replacing interior and exterior lights in my GT. First I want to clarify that the head, fog, side marker, and break lights come as LED. This thread is about interior, reverse and turn signal lights.
Interior: CorkSport has an excellent 8 piece set (2 front interior, 2 rear interior, 2 vanity, and 2 license plate) for $49.99. They also have in excellent .pdf for installation instructions on the website:

I went cheap at Amazon for $26.50

For blinkers I used these which didn't need a resistor for just the rear, but did when I replaced the front also (got hyper-blinking).

These I used for the reverse lamps.

I am now incandescent-free.

I have a set of the iJDMtoy no resistor signal lights in the front. They work extremely well, and are far brighter than the OEM incandescent bulbs.

For the rear, I replaced the tail light / brake light bulb and signal light bulb with these -
JDM ASTAR 2x 144-SMD 7443 7440 Red Bright LED Bulbs Brake Stop Tail Lights Bulbs
The red looks a lot better in the signal I think.

Also got a set of these for the rear to get rid of the hyperflash
1156 3156 7440 LED Hyper Flash Fix Wiring Adapters For Turn Signal

In addition, I went to Advance Auto and got a set of 7440 LEDs for the reverse lights, the difference is like night and day.

It appears that both you and BearlyHere used the same brand bulb, he putting one set of the no hyperflash into the rear, but when he added a second pair, it started to hyperflash...you, installed it in the front and did not hyperflash, but had to use the resistor adaptors when you changed out to the led turn signal bulbs.

So it appears that you can only put one pair of led bulbs (front OR back) before it begins to hyperflash when you add a second pair.
