The search for aircraft-style LED lights in a brass finish is baginning to show (some) promise. www.tjtrailers.com
has a page with ARCON 12 volt aircraft-style lights. Though not with LED bulbs.
Michele, thank you for your kind offer to shop at your nearby Joe's for me...if these are the same lights you're using I'll be able to order them myself.
Michele and Miriam, are your lights Arcon branded lights? If yours are Arcons are they surface mounting or do they need a recessed mounting?
Can you see what type of light bulb your lights use? What I'm trying to learn is the specific model number of the bulb they use to help me/us find out if there's a good warm white LED replacement bulb that will work in its place. The above linked tjtrailers webpage with Arcon lights has a footnote indicating they use a bulb #1003. I googled "bulb 1003 led" and found a variety of possible LED replacement bulbs.
The hunt is on.
