Need alternative to replace rear light.
 

I purchased an undertail and the brake vs. running light difference in intensity is almost nil.

I've removed the pieces, and need to find a place on the web where I can order a new tail light assembly. It doesn't have to be perfect, just close and I will do the rest. It doesn't even need to really be an LED assembly. I'm more looking for an online distributor who has rear light assemblies that come close to this size.
