I would like to fab some custom LEDs Assemblies.

Embed a resistor in the plastic, is there a smart way to go about doing this?

I know Alibaba other than that nothing really.

Custom plastic could be expensive. I would find a lens you like and fabricate a small PCB with an SMD resistor and SMD LED. Glue the lens to the PCB. Add two pins for the external connection.

While will not knocking someone's attempt to rediscover lost arts or replicating the experiments done in the past, it's unlikely you'd be as successful as a modern led. – geo_melb Mar 22 '10 at 9:41
I could be wrong but I was reading this as "I would like to fab some custom LED assemblies". – jluciani Mar 22 '10 at 19:44

If all you want is a led with a built-in series resistor, I believe these are available already.

How many? For anything less than thousands it would probably be cheaper to solder a resistor to an LED and pot the whole assembly in acrylic
