They are a strange type of solder-in incandescent bulb, not sure of the exact bulb #, but to replace them you would have to de-solder the stock bulbs and solder in LEDs w/ resistors probably. Check the member write-up section for an LED swap thread, there are a few of them on the site.
I looked around and couldn't find any relative to my model and make. I do know at 04 or so they changed from #194 to the type I have. I'm not the best with computers, but I've searched where I thought plausible. I've asked Napa, Oreillys, and other various stores and they too have no idea what type of bulb it runs off of. I even called the dealership and they can't look for the bulbs, as the only diagrams they have are for the cluster as a complete set, with gauges and all.
