What could cause my 1989 Mercury Topaz's brake lights to not work when all the bulbs are good?

A defective brake light switch could cause the problem. Also a defective turn signal switch could also. The brake lights work through the turn signals. It cancels the brake light so that the turn signal can work.

Do incandescent light bulbs have more mercury in them than fluorescent?
I would say no. My reasoning is that if incandescent bulbs have as much or more mercury than fluorescent bulbs, the fluorescent industry would be debunking all the reports of a mercury problem.Incandescent lights do not need or use mercury to operate, so there is none in them.Fluorescent lights cannot be made at all without mercury, as it is the glow of mercury ions that produces the UV light inside the fluorescent bulb to excite the phosphor coating to make visible light.
What causes the left tail light not to get brighter when braking even though both bulbs light up when the lights are turned on on a Dodge Stratus?
Many taillight assemblies are equipped with bulbs with dual filaments, one for tail lights and one for brake lights. If you have one bulb with two filaments, then the problem you describe sounds like the brake light filament in the left bulb is burned out but the tail light filament is working.
What element is used for making coloured lights?
Neon. It's actually a sort of orangey-red and not a pure red. Pure red bulbs are probably fluorescent bulbs containing mercury vapor with tinted glass to make the light appear red.
How many atoms of mercury are in a light bulb?
Compact fluorescent light bulbs contain mercury. (For that reason, it is important to be very careful with a broken compact fluorescent bulb, because mercury is highly toxic.) Most other kinds of light bulbs do not contain any significant amount of mercury.

Your brake lights on your 2002 Acura RSX arent working but your tail lights are?
The brake lights and tail lights are separate wiring systems. Even some of the bulbs may have two separate bulbs in the same glass housing. If the bulbs are in fact working, then the next step would be to test the brake switch under the dash. When you depress the brake pedal the switch is pushed creating a connection to turn on the brake lights.
