No.

First verify that your battery terminals, posts, and wires are clean
and intact.

Then I would continue by locating the following ground wires/10mm head
screws and cleaning, checking for breaks, and retightening them:

Engine ground at front of engine just to the left of where the intake
manifold flange and head meet (assuming the 98 Prizm is the newer
1ZZ-FE engine)

Headlight switch ground in the lower driver's kick panel area behind
trim

Body ground in passenger kick panel area behind trim

Ground, front left fender near the headlight housing

IF you are also experiencing problems with the headlights or DRLs or
the blue highbeam indicator light is on all of the time, look up behind
the inside fusebox (driver's knee bolster in dash)for a small junction
connector that has both White/Black and Red/Yellow wires going to it.
See if this connector looks overheated.

And if you have a highly modified car alarm with an engine kill
function that is tied into the headlight switch, then look there as
well (obvious)
