Found the LED bulb for the transom light. it is from here 9 LED Light Bulb - Automotive LED Lights - LEDLight
You will want the BA15D bulb which is a direct replacement for the #90 bulb and is available in 6 colors. Price is $5.99 each but I would suggest ordering a spare or other bulbs you may need since shipping (maybe just me) was $5.95 which makes it a $12 bulb.

I made an error on the gauge bulbs. It so happens that i had a couple of 194 type LED instrument bulbs mixed in with the courtesy light LED's. The 194 type is the correct LED for the bigger gauges. Next weekend I will minaturize myself and attempt to remove the smaller gauges bulbs for a looksee
