my headlight wig wag design

this is my newly designed wig wag system, I'm not a 100% positive if it will work correctly yet but i figured i would post it up to see if you guys saw anything wrong with it, something i missed maybe

basically i used four relays for the purpose of back feed electricity, it basically mean's i can install this onto any car whether or not the head lights are run in a parallel. and i also used a 3 prong flasher relay.

hope you guys like it.

Firstly I am NOT used to looking at physical representations - I much prefer circuit schematics - ie, showing functional switching and paths.

Secondly - I assume the flasher can is suited to drive a mere relay coil?

Thirdly - as I read it, the lower right relay does nothing other than connect battery+ to H (ie - the power output from the headlight switch or relay) in both positions.
And also the upper right relay shorts battery+ through the switch to GND.

FYI - convention is that the more +ve is 86 with GND etc being 85, though this is only important for relays with inbuilt spike suppression diodes (which I never use - I use plain relays with my own external suppression diodes).

Maybe if you explain what you are trying to do is a good starting point.
The available hardware also worth describing (555 or other timing circuits; whether highbeams are relay powered, etc).

Kind of reinventing the wheel here because of all of the headlight wig-wag flashers on the market, and ones that can even have different patterns, and totally solid state so no noise. For total isolation, you can use one designed for Chrysler/Dodge vehicles. Can still be a fun project if you have the time to experiment. Depending on the 3-prong flasher you use, the relay coils may not draw enough current to alternate properly.
