I something similar with both my sidemarkers and my center taillight. It looks really good. But the taillights on a B13 and B14 are 1-piece, so you have to go out and get Tsuru tails on the B13 and SE-L tails for the B14 to get this look.
OK. That can work for our tails...but it would just be like putting in the SE-L tails. And I wouldn't advice anyone to use that office lighting stuff for their tail lights....it breaks easy. I did use it for my third brake light, but thats smaller and not curved, so it wont crack as easily.
As for my tail lights, I did exactly what selrider said. I had the APC clears, and painted them, leaving the reflectors clear. Heres a link to them (msn dont link externally anymore ) http://groups.msn.com/srac/shoebox.msnw?Page=5
