odd problem with headlights

[jst6]

i just replaced the headlights in my 66 with the sylvania ultra white 7" round ($12 each at checker) and now when i engage the brights the right light shuts off. all fuses are good could it be a bad bulb?

Either a bad bulb or the plug is making poor/no contact. Do you have a curcuit tester so you can make sure you have power at the bright terminal of the plug? You could also test it with your other new bulb to narrow down the possibilities.

had the same problem and the bright setting or whatever was burned out in that bulb, i used a light up circuit tester to find the problem

Look for 12V at the green/black wire at the plug.

If it's not there, check the green/black wire at the driver side light.

It should be good if that light is working.

Here is a site that has diagrams:

The high beam and low beam setting of the bulbs have separate hot wires, but share the same ground. The hot wire on the passenger side is probably shorted somewhere. Try swapping the bulbs side to side. If then it happens on the driver's side, you will know it is a bad bulb and not wiring.
