Easy headlight question

On the 3 prong plug, which terminal is which?
I believe high beam is opposite ground and low beam is the one in the middle, correct?

I think you're right but it only works right one way. Keep experimenting. Look at the other headlight. It may be grounded near the light.

hi again. I'm not sure if it matters but some of those old ones were positive ground. Watch for that.
