  Ok, I'm REALLY late in the thread here.  But, I have this really cool 
LED bowtie (Chevy symbol) on the front on my 94 ImpalaSS.  It was built 
by someone else, but it has 38 LEDs inline with resistors between each 
one.  

  A Link to the webpage is www.lisst.com/rbt/body_index.html.  Knowing 
the designer, I'm sure he'd be happy to talk with you about your LED 
lighting questions.
