I think I've mentioned these before - for white headlight indicators you want white PLCC-2 LEDs, either modifying the terminals by bending, or just bridging them with solder. Ebay PLCC-2 LED's: PLCC-2 LED | eBay
(Note - the corner 'notch' on top of the LED means "-" / Cathode...)
Here's a shot of the back of 2 of the boards - left one is the white PLCC-2 LED; note I also replaced the resistor with a 4.7k one vs. the OEM 560 ohm one. 560 ohms is 'ok', but gets hot since it's pushing more current than the LED needs. One of my boards I used 4.7k, the other I used 10k, and both white LED's light up plenty bright. No reason to have to wear sunglasses at night, right??
Board on the right is OEM, notice the front-facing LED.. The PLCC-2 LED just needs to line up with the hole in the board, then solder it down..
Here I added some 3D printed spacers to help with light dispersion.. The OEM spacing has the LEDs very close to the graphics, which to my eye left a bright 'dot' in the middle instead of even illumination. Spacing the LEDs farther back helped even out the light, in my opinion.. Some diffuser plastic behind the graphic would probably have the same effect.
Shot with the boards mounted - NOTE, the top one in the picture above is shorter - turns out when they're this tall, the top circuit board will hit the aluminum of the dashboard... I had to cut it down for clearance.
And lit up - I also illuminated the START button with white LEDs in the center, and a red ring around the outside:
(inside of START button.. Looks cooler in person than in the pictures..
