Blinker fog light mod

I know this has been addressed a LOT but everything I have found is using halogen bulbs for this which I'm not wanting to do and knowing leds use a lot less current I'm wondering if anyone has turned the corner light into a blinker without putting a 2nd bulb in the corner housing and then putting leds with fans in the fogs (like used in headlights)?

 

Are you planning to add another parking light to the front of the vehicle? You need those front marker lights as well. That is why another bulb is added .

Some have just used a dual filament bulb in that location.

LED`s with fans? You need to be real careful with Fog lights to make sure they are DOT approved .

 

I've seen where some keep the parking light and it stays on then when the blinker is on they just dim and get back bright without having a dual filament bulb. That's not out of the question of drilling and putting a different bulb if need be I just want to make sure the corners will stay lit for parking lights then blink regularly with blinkers and not hyper flash. Then I'm going to do something like one of these where the blinkers once were as a bright fog light to help see at night.
