I've a Q about HUDs as well. Is there anyway to make the display brighter? For example, my first two digits are dimmer than my third (100 MPH+). is that just normal wear & tear or is there something i can do about it to make the common part of the display brighter. (I do have the dimmer switch turned all the way up.) I've read somewhere in the forums about changing bulbs? would that work/how is it done?
