Sorry ive make a few mistakes in my post but couldnt edit it.

Low Stimulation, try a quiet tune, short and the same all the time. Even if he crys increase the volume a bit but not to loud just so he starts to listen to you.
Night Light, not to bright, just his bedside lamp with cloth over the top. We have clips on top of ours to keep it off the light bulb. Its been like that for years with no probs.
Routine for bed, bath maybe, jarmies, warm milk or B/F (whatever he has), read a short book, say ok its bedtime now (use your own words), give dad kiss and cuddle goodnight, off to bed. Keep it the same every night. Kids like reputition.

All this has worked for my kids, it may or may not work for yours but its a very simple routine to do that is easy. Good luck with everything. Its very hard to start with but keep at it and it will be so worth it.
