This is a bit premature but I'm pretty excited about it and had to share. I've been thinking about upgrading the dash backlighting to LED to brighten it up and change the color temp a bit. I found the LEDs that will solder in the place of the bulbs and figured up the current limiting resistor values and order them all up. Got the LEDs in today (still waiting on the specific resistors). I just had to do a little bench testing to see how they will work out.
Here is a photo of the original dash lights. It's really hard to take a good photo of them with the point-and-shoot camera changing the exposure all up so I ended up having to video them and grabbing a screenshot. This made for the best representation of the actual brightness and color.
Sorry it's a bit blurry, it's hard to stand still for that long of an exposure. This is an photo and is a bit brighter than actual. This is the screen print over the lights, the rest of the dash is in pieces, that's why there are no needles and the other light seem to be lit up.
This is a screenshot of the video and a very close representation of the actual brightness.
This is just one of six installed. There are two per gauge.
And here is what it looks like with just one of two for this gauge!
When I get all done, I'll do a full write up on it with all of the parts, values, and placement. Cost is about $10 for the LEDs and resistors.
