I have had intrmitten brake lights for sometime[not good] and was told by 
others that the old bulb holders lose there grounds,so I replaced the old ones 
with new ones.NOW,I have side lights front and rear,but NO 
parking/running/brake 
lights I sanded and cleaned where the NEW bulb holders get there grounds and 
useing a test light have NO current at parking/brake lights.I DO have current 
AT brake ped switch,where do I go now???? Thanks Bob
