I just converted all the lights on BOB with warm white LED lights. I didn't find festoon-style LED's, so I bought some warm white 24 LED lights on eBay and soldered them on burned out festoon bodies. They are a bit brighter than the incandescents, and take 1.2 watts instead of 10 watts each. I'm still puzzled how they can ship these from Hong Kong via airmail and still get them in my hand for less than $4 each. I received them 10 days after ordering.
