TR2/3/3A How to wire headlights for TR3

The colors of the three wires at the junction connector inside my headlight buckets are faded/gone. The headlight bulb has three terminals on its rear - which terminal gets the High Beam wire, which gets the Low Beam wire, and which terminal gets the Ground wire?

You could always just try it. There's only 6 possibilities. That's actually what I do as mine are also faded and it's easier than checking inside the bucket every time I need to hook them up.

However, if you look at the base of the bulb and hold it so there is a terminal on the right, top and left; the one on the left is ground, the one on the top is low beam, the one on the right is high beam. Here's a photo I found on the 'net

Sorry for the duplicate post. My browser got hung up and when I clicked refresh it looked like the post hasn't been saved, so I saved it again.

You're repeating yourself! You're repeating yourself!

(Thanks for the photo(s) - I always use the "try it and see" approach myself.)

Actually, Randall caught a typo he made in the first post ("the one on the right is the ground...the one on the right is the high beam"), but some how he didn't delete the first post.
