To change the bulbs in Peterson trailer tail light # 432400 you will first remove the main lens which is held on by 4 screws.

The main bulb can be removed by pushing down and rotating the bulb counterclockwise. There is a diagram on the inside of the case that explains this and it says turn it 30 degrees then pull up. I had to turn it several more times when I played with the light so it probably varies slightly.

To install a new 1157 bulb # 30-90-157 you will line up the lower nub on the light base with the upper slot and push the bulb in. It will snap into place. This is also shown on the inside of the light in a little diagram.

The other bulb just pulls right out.
