im thinking i take blub 1 wiring it up off my accessory fuse panel. i will put some kind of relay and then some kind of delay to time the on/off flash. Should I get a underdash flasher like from a 1978 pinto? just get one of those and connect it to the access. panel?
+battery--fuse block---relay----socket light #1--- relay socket light #2 ---- socket light #3 ---- socket light #4
So would they all need their own relay?
what about setting the delay on each bulb to go in oder.
They still have a timer and logic circuit that drives the sequencer.
They always have... from the time they moved from electromechanical to solid state.
The difference between 1960 and 2013 is the size of the unit, due to the current requirements of the lamps being driven.
You're looking at 1970s-era load levels.
Seriously man... I hate to be insulting, but from the questions you are asking, the comments you are making, and the ideas you are throwing up against the wall to see if they stick, you lack the basic knowledge required to design and construct what you want.
I built what you are wanting to do about 25 years ago. I used a 555 timer as a basis, ran through a couple of other chips... basically created a theater chase-light circuit, then used that to drive a series of transistor cascades to drive the lamps.
It could drive an LED, but the cascade didn't drive the lamps for long before it overheated. Boss ended up buying a replacement controller before I tried to troubleshoot it.
