Hi Nathan,
You might have seen the lights that Roy & I use in his Mk1 GTD, they look thus:
They have six lights and have a remotely located control box that looks thus:
This enables you to set the point at which the 1st and last led illuminate and the unit spreads the others inbetween (if that makes sense?).
The box allows you to set a shift down rpm that illuminates the left hand Green LED when you drop below a certain point - in addition there are six levels of brilliance to the leds you can set, whether they flash when all on, a filter function and so on. The unit also stores six profiles, each of which can have diffent settings (eg. road use / sprint / circuit / driver a/b etc etc). The unit has a peak max (absolute maximum Rpm recorded) and a smartmax which filters the input against time (also adjustable) so it records peak revs in gear on load as opposed to 'missed shifts' (something I managed on each of my three runs at the AMOC Sprint yesterday at Goodwood - oops)
The unit can be hooked to just about any ign system and if you have problems, the mfrs provide excellent support. NO, before you ask I'm not on commision but the unit works great and therefore deserves good critique. Dave Parker also uses it in his R42 as does Julian in his GTD.

Finally - for a more discreet installation - why not consider an installation like Andrew Fordyce has in his GTD MK1. This uses an SPA 3 digitally controlled 3-light system. I modded this to replace the supplied display unit with three high intensity LEDs that were then mounted in small dash mounted clips between tacho and water temp guage thus:
This keeps a period look to the car but gives the bonus of a bright shift light (When off you don't even notice them)
Hope this is of use.
