head light 'flicker'?
While simply checking all my lights on my '63 Impala, I noticed the tail lights were not working with the switch in the 'headlights on' position. They did illuminate with the switch in the 'parking lights on' position. I reached under the dash and 'fiddled' with the connector to the switch and all was operational.
Today I pulled the headlight dash switch to do a house keeping on the connectors. Cleaned up everything re-assembled and re-installed. Everything was working as it should; almost. With the headlights 'on' AND the turn signals engaged, I noticed a VERY slight 'flicker' of the head lights 'in time' with the turn signal 'blink'. Looking directly at the head light bulb, I don't see the 'flicker' (with my old eyes). Looking at the garage wall is where I 'see' it. The 'flicker' is SO fast it is ALMOST imperceptible. I do not notice any 'dimming' of the head lights.
I am not an electrician. What could cause that?
It may have been like that before I messed with it, I do not know, I didn't perform a tun signal test w/headlights on.
