I would try finding all the ground wires on the vehicle and cleaning them to make sure they are getting a good ground. 12 volt systems are very sensitive to bad grounds. I seriously doubt that turning on the light had anything to do with it, but a bad ground could give low voltage to the radio, relays, etc. and make them turn on and off. The more things you turn on the more the bad connection will give problems. I hope this helps.

I believe it's one of your relays too. There are a few relays under the glove box. If you can determine which one is clicking you can change it out and possibly solve your problem. Good luck...

1.Loose Battery cable. Very common thing for a side post battery.

Solution: Tighten both battery clamps as needed.

2.Corroded connections for battery cable ends. The cable ends that connect to the battery.

(A side post battery was a bad idea IMHO.

When a battery is made the posts come up through a plastic case. There is a seal around the post, under the plastic case that you cannot see.
This seal allows battery acid to eventually leak out.

It was bad enough for a Top post battery, but seems like a ridiculous idea placing the posts on the side!
The idea was implemented to save space, so that cars could be made smaller)

Solution: Clean battery clamps, and side post area on battery.

SAFETY ADVICE!!

Hand Protection:
Gloves should be worn when working with a Battery.
Dishwashing gloves would work, but be sure to replace them, if a hole is torn while you're working.

Thin leather gloves are preferred.

Clothing:
Use old clothes that you do not care about, and may be thrown away if needed.

Eye Protection:
Safety glasses, or goggles should be worn. If safety glasses are not available, at least wear some sort of eye protection.

As said, battery acid does leak out. Usually a tiny amount, and not always seen. Even if dried, it is still potent.

This is Sulfuric Acid.

It will eat holes in your clothes. You won't notice it until you go to wash your clothes.
It will burn your skin, and eyes. DO NOT touch your face until the gloves are removed, and you have thoroughly washed your hands.

Use cold water first. Warm water will open the pores of your skin.
After using cold water, and thoroughly cleaning your hands, then you can use warm water.

When disconnecting a Battery, ALWAYS disconnect the Negative terminal first! Positive terminal last.

When connecting, Positive terminal First, Negative terminal last.

You can use a solution of Baking Soda, and water to clean the battery clamps.
Two tablespoons of Baking Soda to a 12 ounce glass of warm water thoroughly mixed. (It won't mix all the way. Squish it around in the glass as you are using it)

You Cannot use this mixture on the Battery. There is a chance it could go through the seal/s, and will nullify the battery acid inside, ruining the battery.

A wire brush is used for this application. (One of the reasons the eye protection is imperative. The wire brush bristles could sling dried battery acid up in your eyes)

3.Bad battery:
Could be the battery is at, or near the end of it's 'Lifetime'.

4.Bad Alternator:
The alternator isn't working, therefore isn't charging the battery.

5.Loose or Worn Alternator belt:
The belt/s are worn allowing the belt to slip on the Alternator pulley.
