Do the lamps toggle, but just don't lock on? Are the headlamps on when this happens, if not it is flash to pass. The concern could be as little as a loose dimmer switch, or lost adjustment. The linkage rod from the column down to the switch could have came dislodged, or there could be a problem in the column. Steering column work requires quite a few special tools, like a steering wheel puller, a lock plate compressor, if it is telescopic you will need a set screw to lock it. The dimmer switch is mounted external on the lower part of the column by the ignition switch. Is there any looeness in the column, it may have contributed to the concern. Usually a result of the lower bowl retainers coming loose, or the tilt pins backing out.
