Hi,
Installing the wiring on my 27 headlight bucket, there are two wires, black with red tracer and black with green tracer. Is there a difference which screw each one is attached to? The black with GREEN tracer is indicated as the low beam. I'm wondering if I have the wires at the plug reversed. Does it make a difference? Does the bulb care which contact gets the one with the GREEN tracer? Thanks,
John

Just attach the wires to the terminals. Doesn't matter which one... It only matters after bulb installation. When switched to dim, if one bulb is brighter than the other, just remove that bulb and reinstall after you turn it 180°. .... If you feel that that is wrong, just reverse the wires on that bright bulb socket, then reinstall the bulb so both have the same brightness on dim.

There is a correct way to install bulbs. There is a center filament and the other is off center. The off center one goes at the top. The wires at the back need to be switched not the bulb. The off center is low beam.

NY John T . .. Even after the correct bulb installation, and one headlight is brighter than the other... Just disconnect the thimble socket in back of the bucket, rotate 180° , and reinstall to get both bulbs the same brightness

And if you still have a difference after applying Robert's suggestion, you may have a ground problem on the dim side. Solder a wire between the bulb socket in the lamp to one of the rivet heads inside the bucket. Do both sides to be sure.

Thank you folks,
I looked carefully and I don't see a filament that is off center; unless my eyesight is worse than I thought. It's hard to see a real difference when I put the lights on during the day or early evening, while looking into a crowded garage. I guess I would notice more if I aimed at a blank white wall. So the filaments themselves (within the bulb) are oriented in a horizontal position, correct? That way would give a flat spread of light, correct?

John, LEDs don't have fillaments to align. The spread of the beam is achieved by their reflector. Either the socket into which the bulb is fitted is a little bit off, or the headlight stem needs a little bending.
