QUOTE(914 RZ-1 @ Sep 30 2020, 02:16 PM)
I'm thinking of doing the same thing for my car. My turn signals are not bright enough for me and the interior lights are too dim as well.
Questions:
1. Do the LED's need any sort of resistor/other mod or anything to make them work with the existing wiring, or are they truly plug and play?
For the most part, they are plug and play. The exception is the turn signal flasher. You need an LED compatible or you will get hyper flashing. Spoke has a
tech article on his site that tells you how to modify an EP26 flasher from your local FLAPS to work for the 914, or you can just
buy one he has modified for you. One other gotcha I discovered is that when I replaced the brake warning light and turn signal indicators in the instrument cluster with LEDs, they hyper flashed. It didn't affect the function of the bulbs but I found it annoying so switched those back to incandescent. Also, the alternator indicator light needs to stay incandescent. I think you can put a resistor inline to compensate for an LED but didn't seem worth the trouble to me.

2. When I looked up the lights for a 914, I clicked on the rear bulb just to see what happened and I got two choices: a CAN bulb and the recommended one. Which ons is for a 914?
I just bought the recommended bulbs and they worked fine.

3. They have colored bulbs. Should I get those of go with white?
For the most part, I don't think it makes a difference. I bought colored bulbs to match the lens colors with one exception. I compared the red LED tail light bulb on one side with a white incandescent in the other and couldn't see any difference in color. I didn't try a white LED behind a red lens though to see if it was still the same. The one exception to color matching is that I put red bulbs in the rear side marker sockets and am running European lenses that are amber. The red bulbs dominate so when the running lights are on, the tail lights look like full on red American lenses making them US DOT compliant. When the turn signal comes on, it flashes bright amber so a really nice contrast from the red running lights. Pretty cool really.

4. How is this option different than going with the LED light kits sold by Spoke (I think that's who sells them)? Or are they just another option?
Spoke's lights are full plug and play replacement panels so much brighter and a more substantial upgrade. I wanted to stay close to the stock look while brightening the bulbs and reducing energy consumption and am very happy with the Super Bright LED bulbs. It is also affordable. My order to replace every bulb in the car other than instrument illumination was $122 shipped.
Hope this helps
