Hi,

I am trying to to setup a little LED display thing that will show me what lights are on. For example, i want to make it so when i turn on the headlights, an LED for each light will turn on and i can tell if a light bulb on the outside of the truck is burnt out and because i think it will look really cool. Its a 2004 GMC Canyon and so far trying to work with the electrical system has been REALLY annoying becuase its all run through so many computers. Anyone that could assist me in going about this please respond. Thanks,

Ryan

Fiber optics to each bulb, no electronics involved.

Amp meter on bulb circuit - some electronics involved.
