Genuine Buddy 150 running lights help

[Caveman65]

Hey all. New to scooters. I'm fairly mechanical given proper instruction and can hopefully follow electrical advice as well. I got my scooter used off CL. My scooter has aftermarket USA front signal lights. The stock signal lights have been wired to run as running lights. I have a whole bunch of questions.
1. Should I switch these to LED's to put less drain on the battery?

2. If so, what are the bulbs that I need? I'm pretty sure they are #1156, but there seems to be a bunch of different looking LED's with that number.

3. Do I need to add a voltage regulator designed for the LED's?

4. Ideally, I would like to use the rear signal lights as running lights as well. I noticed on Youtube that Voodoo Scooter Parts has a front-to-rear wiring harness kit for this purpose, but when I went to their site it says it is closed indefinitely. Any suggestions?

5. I think I need some sort of Universal Relay as well (?) to make the rear lights work as both running lights and signal lights?

Thanks in advance for taking the time to help me out. Much appreciated.

Peace to all.
