2012 Ford Fusion High Beam wig wags

Asked by Moto Oct 29, 2017 at 03:04 AM about the 2012 Ford Fusion SE

Question type: Car Customization

I have a 2012 ford fusion SE that I have about to install high beam wig wags
on. The problem I have is that if you supply power to one high beam, its
supplies power to both high beams. So I would have to isolate the headlights
from one another in order to install the wig wag that I have. Is there a way to
do this without causing issues with the factory wiring? If so, how would I go
about doing it? Also, is it a ground side  or positive switching headlight set
up?

As I research more, I believe that what I am trying to do can be accomplished with diodes. Now I just need to find some diodes that can handle the wattage. If I can do that, I should be able to put a diode on the positive wire just behind the left headlight but in front of the positive wire to the right side and then put a second diode on the positive wire going to the right. If it works, I should be able to tie in on both side between the diode and the head light... Does this seem like a reasonable plan?

I don't know much about diodes but I was under the impression that zener diodes aren't forward bias. I was looking into schotkky diodes because they have less resistance than standard silicon diodes. Based on what I read, the high beams should be about 65 watts. And since amps x volts = watts, I'm thinking a 1 amp 100 volt schotkky diode should do the trick. If my information is incorrect, please let me know cuz I only want to have to do this once.
