lighting heavy mobile game optimization

Hi, I am creating a mobile game, where everything is in the dark , and I am mainly using point lights to make game look nice. The problem is that these lights are so expensive on mobile , I am getting only 25fps with my SGS4 with scene you see below. Also I am using unity free.

My goal is to optimize it so I could have levels with big amount of "glowing" objects(20-30) and still gave a decent amount of FPS, perhaps 30 on my phone. I searched about light optimization , and found about baking, light probes , but I am not sure if I can use them in such game. It can be fake lighting , using some tricks, the only requirement is to keep graphics nice enough.

Basically there are 3 types of "glowing objects" :

1. Checkpoint (long green or red line) this kind of object is never moving, it can only change color to green/red and turn off completely. (currently I use multiple point lights on it.....)

2. Coins. These objects also don't change their xz position, however
   they do have hover movement (they are constantly moving up and down a little bit)

3. Enemies. These are hardest ones. They are constantly moving.

Notice 2 things I want to keep(but I can sacrifice their quality)

1. Floor, I want it to appear bumpy

2. reflections on the floor and walls, notice reflection on the floor below a coin

Any tips and tricks are appreciated, names of the techniques are enough, willing for your help :)
