I had a bright pink helmet. I nearly got hit from behind I can't remember how many times. People pulled out in front of me more times than I can count also.
This spring, I got a new helmet: a Scorpion EXO900, HI VIZ YELLOW. I wear a hi viz yellow long sleeve shirt with reflective material all over it.
On my way to work the other day (a whole 6 miles), 2 people pulled out in front of me and one turned the corner and almost hit me from the side.
I'm not sure that adding more lights will help but it's worth a try. I'm seriously considering it myself. Plus adding flashing brake lights.
