Review on CEC Industries PC579 Printed Circuit by Bill Pulakanam

The original PC579 bulbs used in many Chrysler and Dodge vehicles were made with the bulbs permanently connected to the socket contacts . While the glass bulb can be pulled out of the plastic base, it is difficult or impossible to insert a new bulb since the wires on the lamp base must be disconnected and then connected to the pins; It can be done if you're careful and experienced, but it's not as easy as it should be. However, with these replacement bulbs, the sockets have contacts for a regular #912 or #921 bulb, so they can be reused - and better yet, you can swap out your glass incandescent bulb for a much brighter, cooler LED bulb. what I did.
