I know Tamiya makes tranlucent colors like red yellow and blue. I'll get some yellow and se eif that helps tone down the blue. Although my lights only really look blue in teh video. In person, they look damn bright white.
I use 1k ohm 1/2 watt resistors with mine. The one in the video is without resistors. Power coming straight off two 1.5 volt batteries. Yes, I can dim the LEDs from my decoder as well. I just donto play around with the electronics as much. Like you. Electronics is not the fun part for me.

You can get 0402 LEDs that are .4 x .2 mm. A guy that goes by Ledbaron on eBay carries these. They will fit in any ditch light housing. Thanks Chris. have some coming. RJ |

I see ledbaron only has the 0402 pre-wired in pure white. I've gotten the same in warm white from them in the past. They don't seem to stock those very often. (?)
Mark.

I had that issue last time I ordered. |

I had that issue last time I ordered. That's the tough part - finding the 0402's in warm white. As I said, ledbaron on ebay does stock them from time to time, but not too often. I contacted them recently and they said if there is enough demand, they'll run so more. So, c'mon everyone - send ledbaron an inquirey about warm white 0402's, maybe we'll get them sooner rather than later .... Mark. |

Okay Mark. My bad assuming warm white is common on that site. Did not get the relation to the part number.
Sending them an inquiry about 0402's.

Brian, have to ask, you’re using the rectangular LED’s? How the heck do you hold onto these LED’s while shaving them down. I have a clothespin that I flattened to a taper. Then got an old fly tying clamp to hold the clothespin together and use a jeweler’s file. Got some of those LED’s from Ledbarron, keep frying them on my double AA test stand, so going with the rectangular LED’s.
Thanks RJ

I use a very small machinist vise. I cut a piece of styrene to use as a gage so that when the LED was set on top of the styrene and tightened in the vise, only 0.010" stuck out the top of the jaws. I then used a sharp knife and sliced off the 0.010". I did not slice it all off at once. The coating is brittle and if you slice to much at once, you chunk it off. So slice a couple thou at a time until it was all removed to the top of the vise.
