I've split the lenses from the light bodies and cleaned the lenses up with some cutting compound. I'm currently cutting some black Correx sheet to fit into the lenses as I want to retain, but not use, the reflectors, but I want a black background to the DRLs.
I've some LED strips that I'm going to use as the lights but I'm going to double them up.

I'll take some progress photos if anyone is interested.
