Victor thx for your advice ,,,, I have all 12 volt system whole car
I wrote this in my post above and agree with you...(I think I will change my rear brake lights to LED and then that should take care of what flasher would make all 4 corners work,, agree?)
One can read a lot of articules about how to wire in turn signals ,, I read one that said if I use this peticular flasher I can keep my regular brake lights..
it really hard to find the proof of what works,, when I do i will share it with all
I appreciate all replies , all helps
