There are some really nice 1157 direct replacements that work, it's the route I went. Has CREE bulbs facing directly behind as the brake light and six less intense side facing bulbs that hit the reflector for the running light. I linked them somewhere on the forum, from Amazon, like $25 for two of them.
I went with custom dynamics license plate frame with integrated plate light, turn signals, and run/brake on it. That paired with the 1156 LEDs in the saddle bags as turn signals. Gives me high and low mounted turns and high and low mounted brake light, so no excuse if people don't see it.
For the front I'll be replacing the stock signals with wrapped LEDs just under the bottom triple tree, and using the amber halos in my headlights as run/turn, so same deal, both high and low mount turn signals up front.
As a project IV been considering some two foot long LED modules under the bike, attached and hidden to the oil pan to make my left/right glow under the bike at night as turn signals, impossible to not see for cars. Maybe dual element white/amber with white as running lights and amber as blinkers, not sure yet.
