Just do it!
If you feel like it is dialed In and you feel confident
That it will make it. Well nothing should hold you back. You put enough time and effort into this rig go for it.
I have read somewhere you can use either or on which lights you want to blink. By adding a wire to the apron lights being they are single filament bulbs.
The fender lights are usually double filament bulbs.
Your fender lights are GY/WB. The apron lights are both WB and GB. Hope that helps.
