The backlighting on my '99 Softail's speedometer/odometer is so bad that in low light it is impossible to read. All I have is a faint yellowish glow that is worthless until it is pitch black outside. Is there a way to increase the amount of the speedomter's internal illumination? I'm sure a higher wattage bulb(s) is the answer but the speedomter seems to be a sealed unit. Any tricks of the trade or recommendations out there?
