Headlight turns on

[soublier]

Recently purchased a Nissan Safari 88. Guy I bought it off said it may have an earth leakage. The batteries would drain for no apparent reason if it had been sitting for a few days. Both batteries were getting weak CCAs so I had them replaced. Also had the auto electric guys in Melbourne ran tests to see if anything was drawing current when the car was off. Nothing... I know zero about electronics but once in a while I will see just the front passenger side headlight come on and stay on until I flick the headlight controls on then off. It happens only once in a while. Could moisture be causing this? Faulty wiring? Thanks in advance for any help.

Highly likely that it will be the headlight stalk switch.

Not sure if giving it a squirt with CRC would fix it.[stalk]
might want to price up a replacement

X2 with Winnie.
Heaps of threads on here on how to pull down and clean the stalk switch.

I would strongly recommend inspecting the Head Light plugs for any sign of overheating

Thank you all! Sounds like a great project for my time off this week :)
