Thanks for the help guys.

Designing and building one is an option, but only if I can't find an already designed solution. There are a lot of voltage level IC's out there and "kit" solutions, but it needs to be a very complete and robust solution. It will be living in a test cell environment and needs to be very reliable. So, it would require circuit board design, prototyping, beta units, final production...all things I would like to avoid due to costs and time.

I know it requires more than just a simple LED, but I didn't know if anybody here had any experience with something that already exists. The unit we found was a nice large LED, housing made of machined aluminum, with simple jumpers on the back to select the voltage level, and small terminals for connecting wires. It is very nice, and cheap (<$40), but just is not bright enough. We are in discussions with the supplier to try and recitify, but I'm just trying to find other options to fall back on.

And mechanicalbrain, I've googled everything I could think of believe me. The circuit you show would not work because it would require modifications for panel mounting in the box... Thanks for the suggestion though.

Thanks again for the help everyone... I appreciate it...
