The 194 bulb is ~3.8 watts, at 14 volts they draw 0.271 amps.
Halogen is about 20% brighter.
That depends on so much more then just the watt of the bulb, but if you have two identical bulbs where the only difference is the amount of watt, then logic dictates that 25watt is brighter then 10watt
The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
A 100 watt bulb will normally glow brighter than a 50 watt bulb as long as you are comparing similar style bulbs. You have to compare Incandescents to Incandescents, Fluorescent to Fluorescent, LED to LED, and so forth. You also have to make sure your bulbs are similar in light patterns since you can have general dispersion lighting, spot lighting, flood lighting, and so forth. So, once again as long as you are comparing like style bulbs, yes a 100 watt bulb is brighter than a 50 watt bulb.
They are the exact same size and you can use them interchangeably. The diffence is that the 168 will be brighter than the 194. Although it is brighter, the 168 will not last as long (1500 hrs) as the 194 2500 hrs. - edit - The 168 has 3 candle power vs the 194 with 2. Since the 168 is slightly brighter it produces a bit more heat (3.8 vs 4.9 watts). In most situations where 194's are specified you should use an exact replacement to avoid heat damage from the hotter 168 bulb.
The Shorter the wire the brighter the bulb ! Because if it is short then it get brighter and the more batterie the brighter the bulb ! Or the lower voltage the brighter the bulb !
no
Remove the 2 screws that hold the plastic lens, pull out burned bulb, push in new one (#168 or #194), verify if working, reinstall lens.....
If the current is stronger then the bulb will be brighter.The reading is much easier when you sit under the brighter bulb.

more battery's or a better bulb.
That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.
The bulb will get brighter
pop off the carpet trim from the trunk hatch. there are three 8mm or 10mm nuts that hold the upper license plate trim containing the bulbs. the center one also holds the trunk latch. remove these and pull the whole assembly out. the bulb holder twists out. replace with a 194 bulb. use LED 194 bulb for longer life and brighter light. you can also get different colored bulbs to customize @ www.superbrightleds.com
Usually a higher voltage will make a light bulb shine brighter; but if the voltage is too high, this can also destroy the light bulb.
A brighter future!
