What are the "low, medium and high" lights for?

 

they're the acd indicator lights. i believe they're marked gravel tarmac and snow(not 100% sure though)

 

I would be interested in the standard set - white with black numbers. Is installation a pain or easy? Do not have an extra guage package available either.

 

High = Tarmac
Medium = Gravel
Low = Snow

These grades refer to the highest potential locking ability of the ACD center diff in each mode.

 

I'd like to know why some of the sponsoring vendors here don't step up to the plate and have SR Motorsports design replacement faces for the Evo. Don't they think they'd be able to sell ten sets and recoup their investment in a heartbeat?
