I think the stock lights and fixtures look dumb. I did find this light that I'm sure will make the center light look fine https://hogworkz.com/blackout-7-inch...headlight.html ... but I can't find anything to replace the bulky signal lights. Where should I be looking? Picture of my bike for reference.

 

One of many options

 

Lots of options for signal lights at J&P Cycles, Custom Dynamics, etc. You could leave them in the current spot or relocate to the forks. Just be aware that you'll need a load balancer if you switch to LED lights or you'll have hyper flash.
Originally my Fat Boy had them mounted on the handlebars. Never cared for that and got them relocated to the forks.

 

Not a softail, but you get the idea.

 

The vendor you got your headlight from has options for the other lights too....

One thing I'll say about Hogworkz - they've backed up their product in my experience. I have a set of their Softail Conversion bags on my 2002 Fat Boy. About a year in one of the brackets cracked all the way through at a mounting point. They replied to my email on a Saturday and the next week shipped out new brackets for both sides of the bike.
I also have their Halo headlight and Uproar tail/sequential turn signal light.

 

I installed the same front turn signals on my 2006 FLSTC. IMHO, they look much better than the stock flat lenses.
