Zusammenfassung:A lamp and lamp driver are disclosed, in which single intensity marker lamps that are desired to be flashed can be connected to a lamp driver employing an exclusive OR (XOR) logic circuit. In one application, this lamp driver is coupled to a vehicle turn function wire and marker function wire, and a plurality of marker lamps in a row can be of the same style, but one lamp can be flashed in the row of marker lamps. In some embodiments, if all of the marker lamps are on, the lamp being driven by the XOR driver circuit will flash out of sequence with the turn signal flash. If all of the marker lamps are off, the lamp being driven by the XOR driver circuit will flash in sequence with the turn signal flash. Other embodiments are disclosed.
