I recently purchased a Model A tail light from Lowbrow Customs for about $50. Check out the deal I found here. These guys specialize in stuff like this.

I ordered the 1933-36 standard (non LED) tail light on Saturday and it was delivered on Monday. But that's probably because I am about an hour away. The quality is great. Not a single flaw and half the price of a motorcycle website.
