Want to get rid of the integrated LED brake light bar i have, way to hard to see in the day.  Instead wanna add get some two bullet turn signals with Running, Braking, and turn Functions. Now i know they have to be Dual filament bulbs. That's about where my knowledge runs out

Now what do i need to do to get these to work properly?

I'm pretty sure guys have done it with double filament, and using a trailer converter, but they have to add something i think to slow down the flashing?

I'm a little over my head here as far as the electrial goes, so hoping someone has done it before, or know's an easy(ish) way to do it. My dad's bidgog had two bullet lights that functioned as Run/turn/Stop lights, so it has to be possible

That is exactly how they are wired by Bluecollar bobbers.  Ill get back to you for I will review it first.

Couldn't i technically get a Trailer adapter, run the wires for the brake into it, and then run them to the turnsignals? Not to sure here
