From left to right at full illumination at dial @ 12 volts:
Incandecent 4 Watt (SWISS via India) / LED White (ETarga) / LED Vintage (ETarga)
That 4 watt has the typical yellow hue of the OEM, much brighter than the OEM 1.7-2 watt blubs. The LED White is, actually white and no blue hue like the past LED want to be white LEDs, even the needles appear brighter. For you OEM/Concours type you will love the LED Vintage, they have the coloration to mimic the incandecent hue, but some reason on my 3.2 it came out a bit green
The Dimmer TEST:

The LEDs require a minimal current before shut down, but those worried about too much light can dim them to 75/50/25% only the 4 watt blub can still operate at 10% as seen on the video.
Jake aka ETarga is awesome, he sent them right away and the 1 year warranty is a Bonus. Who does that for light bulbs???
I highly recommend ETarga's LEDs!
Oh yeah no cracking open you gauges, Doh too late for me
