Your dashboard lights will dim because less electricity is available to power the dash lights. A vehicle only has a finite supply of electricity at any given time. Any electrical device that is on reduces the overall electricity available to run other electrical components. The drop in available currrent is not noticable with most electrical components, but can be quite noticable with lights, especially if you have a weak alternator. I wouldn't worry about it if the dimming is minor, but if you are concerned about your alternator, go to Autozone or O'reilly auto parts. They do free alternator and battery checks.
