Check the ground wires going to the headlight bulbs, the grounds may be bad feeding voltage back to the other bulbs (or filaments).. You should find one single wire at each socket that does not go into the wire loom, follow it and it should terminate under a bolt 6"-12" from the bulb socket.. Remove the bolt and clean any corrosion from the wire lug and the bolt.
Blinking bulbs can be caused by too high of a wattage (IE high power bulbs) that the vehicle was not designed for.. Typically headlight bulb circuits use auto reset breakers instead of fuses..
Overloading the circuit with higher wattage bulbs will trip the breaker, the breaker interrupts the current and the breaker cools and resets. Lather, rinse and repeat.
I think you have the answer there. The bulbs are original. I will look for that ground. The ground wires are brown and there are three of them per side on the inside of the fixture. I will find where they come out of the plug and trace it. If I can't find where they connect would it be OK to ground them to the chassis myself?
Would a cracked wire or corroded connection have the same effect as an overload? I understand the cycling breaker and I am sure that that is what is happening although I can't locate one. I'll check for ground first and get back. One thing at a time for me.
Thanks
