Yeah sorry about the lack of automatic information. We have one auto in our whole family, and that's my youngest brother's. The rest of the fleet is entirely manual. I haven't driven an automatic in years...
I know some other people with Rangers (and have auto's), maybe I can offer to change their bulbs for them and get the true complete'd faq.
I used the single LED ones with the 120° angle, mine light up just fine? If anything they're brighter. I haven't messed with the ones in the radio area at all.
Here's my Gages with "Bright White" LED's. It is actually a bit brighter, I have a cheap camera.
At some point I'd like to fine tune the cluster and actually get back to the green, but that's a little ways off. And yes, the filter is actually a blue, not green. It shines through green because of the yellowish light of the incandescent bulbs.
