OK, I HAVE BEEN TOLD THAT IF YOU USE A BRASS BASE EXTERIOR LIGHT BULB ON A BENZ THAT IT "COULD" COOK THE CRUISE CONTROL AMP OR AT LEAST MAKE IT INOP-ANY TRUTH TO THIS???

On older model MBs, the taillights were used as a ground for the cruise control, etc. So if you have the wrong bulbs, then yes, it will cause the cruise control to not work. You should use Osram bulbs, with the silver/chrome like base. They are not that much more expensive, I usually pick them up at the dealership.
