oooh!!!
YES!
This is exactly what I wanted to do, but have them as park lights!
I bought 2 WHITE 6000mcd LEDs from Jaycar, and some matching resistors... Behind the fog light bit is a small rubber elbox, pull that off and there's enough diameter to squeeze an LED in it!
BINGO!
Hooked the LEDs up to the parker circuits... works... Like Joe said, they are the size of a pin and dont give out much light. I want to drill into the back of them to allow more light through, but couldnt get that indicator assembly out to do it.
I'm going to give it another shot on the weekend. However, the white leds look awesome already
