Thanks for giving so much information. It all points to a defective ground circuit in the lighting systems, just for a starting point in diagnosis. Do you say that the problem started when you had the alarm and stereo work done? It's very common for a stereo/alarm shop to mess up the electricals, I've fixed many of their screwups in my day. Naturally they don't want to admit responsibility for the problem, they know that they can't fix it...
I'd say, go to an auto electrical shop or a Mazda specialist and keep away from stereo shops. Sorry, guys, I've seen some bad electrical work from those kind of shops. Just sayin'...
Find an electrical shop or Mazda guy and give the bill to the stereo shop. Won't help but they should know what they've done to your car. A good electrical guy can usually fix these kind of things pretty quick..

The only bulbs I can find to replace are the turn signal and the backup light... no bulbs for the brakes.
New bulbs, correct sizes, but keep blowing fuses. Any advice?
