Hi,
I built a custom power supply for my indiglows. I didn't like the greenish/blue that the stock one put out. Too see what I mean, check see what yours looks like compared to the High Beam Indicator.
Some pics...
The new power supply runs at 10kHz instead of 1kHz. It's an old-school inefficient design, but it works. If there's enough interest, I could post a schematic. Also, I used Kingbright 10,000 mcd X-Bright LEDs for the guage needles.
I'll have to use a tripod to post some clearer pics.
BTW, check out my headlight switch. It matches everything perfectly.

Later,
Ben
