Whats the 'practical' reason for installing huge rims? or a bad-*** sound system?

Seriously though, why do trains have them?

 

Good one.

 

RamSS/T, I agree with wanting to keep it looking clean.

The red switches just would go with the look I am going for.

Is that push button illuminated? If so, is it the same as the instrament cluster?

 

It is illuminated but its yellowish/orange. I chose not to hook the illuminated part of it. I may go back and hook it up but you really dont need it.

Also I have it the horn trigger wired were its always hot and the switch is the ground. That way the switched wire doesnt have to be fused or anything.
