Hi everyone. I searched all over the forum to see if this was talked about before, but didn't find anything, so I apologize if this is already widely known. Since I couldn't find anything I thought I'd try and give a little something back to the forum and help out anyone else who may want to accomplish the same thing easily and for only $17. So, anyway... ***Imporant***- There are a lot of LED bulbs that look just like the ones I used on Amazon. A lot of them are only rated 12volts and you should NOT use those bulbs because they will likely burn up. The bulbs I linked to are rated up to 28volts, so if you're not going to purchase the ones I linked to, make sure you get some that are rated at the very least 18volts. I picked up a Spline case last weekend and wanted to convert it to LED lighting for a couple of reasons: 1. It gets really hot inside the case with the standard bulbs. I didn't like this. 2. I really wanted a cooler temp lighting (color of the light) for the case. The only thing I could find about converting the case to LED lighting was to rewire and add an AC to DC converter to drive the LEDs (LEDs don't like AC). I was fully prepared to do this, but went looking for an easier way. It's actually much easier and doesn't require any rewiring at all. It's a simple swap of bulbs. Well, the correct bulbs anyway. I found on Amazon that there are some LED bulbs that should fit the OEM connector. That's fine, but doesn't fix the AC to DC conversion. They do have some LED bulbs that do the conversion in the bulb though! I was excited to see this, so I ordered the bulbs. I got them today and put them in the case and they work perfectly and fit nicely into the circuler bulb receptacle. They light up the case better than the standard bulbs, have a much better color temp, and don't cause the heat inside the case while they're on. And more importantly, it required no modification to the case. From what I found there were two different bulbs you could get. One was a warm temp, which will have a yellowish tint like the standard bulbs, and the cooler temp, which is a true white light. I got the cool/white bulbs: http://www.amazon.com/gp/product/B00VL9ISKI?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00 The following shows what the bulbs look like. You can see that one side has all the LEDs and the other has what I believe is the AC to DC converter stuff. Here you can see how well they fit in the bulb receptacle in the Spline case (from my actual case): So, I'm really happy with it and it didn't require any modification to the case. I thought I'd put this out there in case it helps someone else that may want to do the same thing.
