lights run om batt voltage. if the're dim the volts are low. something is dropping volts. resistance?, bad conn?, wrong conn? something that buzzes AND drops volts!
who hooked up the switch? where is it fed with batt volts? is that the right point?

if you conn the sw to the cigar conn they should be full brightness,IF they are grounded well
lights otta be simple. i stuck 3 in my lower grill. no sw yet. when i stick the wire in the cigar conn the lights are BRIGHT,no buzzzzzz
