I just can't get it right for the life of me, from what I've read the tab needs to be in the 6 o'clock. I've got it there and both lamps are firmly pointed tight to the ground. What else am I missing?

 

The highs and the lows are opposite from each other. I can't remember which is which.

Loosen the spring clip

Rotate them while they are on. When you hit the "Sweet Spot". you'll know it!

Replace spring clip.

They don't get hot and it's only 12VDC. You won't get hurt.

 

The tab on the low beams should be in the six o'clock position. They don't just fall into place. Be certain that the bulb is seated all the way in. It should lay flat into the fixture. I replaced my bulbs but did not get them flat.

 

If you have them on you can see the little dot shadow that should give you a good marker to go by. Check This Thread it may help you out.
