It is in the headlight switch. There is a small piece of metal shaped like a hurricane weather symbol on the back of the switch, inside the switch assembly. The metal completes the circuit when you pull out the switch. The problem is, it is just glued to the back of the switch. You can disassemble the switch, and use a VERY small screw to attach the metal piece to the back of the switch. It is tedious work, takes about a half hour, and some dash disassembly, but it will cost less than a buck for the tiny screw. Or pay the $60 for the new switch assembly. You still have to take the dash apart, so try to fix the switch first. I did this over a year ago and it works great. I tried super glue first and it lasted 2 days. You need the screw!
Check ground circuit
Most likely the problem is faulty brake light switch.
Have your alternator checked out.

Loosed ground, short on wire, faulty light bulb. Most likely cause, if all the lights are affected, is a faulty light switch.
If the alternator is not the issue, it could be a problem with the voltage regulator, wiring, or a faulty battery. Have these components checked by a professional mechanic to determine the cause of the pulsing headlight and interior lights.
