The 2005 Dodge Ram features a composite halogen-encapsulated headlight. It inserts into the headlight assembly from behind. While it's not one of the easier headlights to replace, the procedure for the Ram is doable and after the first time replacing one, you'll be quicker and more knowledgeable for the next installation. You can purchase the headlight at any auto part store.
Open the hood.
Remove the expanding headlight fastener retaining screw (located on the upper/inner corner of the assembly) with a Phillips screwdriver. Remove the fastener from the headlight assembly welt.
Use a ratchet and socket to remove the two retaining bolts on the inner side of the headlight assembly that is located near the grill.
Remove the last retaining screw located on the outer-lower edge of the headlight assembly between the assembly and the fender. Note that on the driver's side assembly this retaining screw also retains the ambient temperature sensor.
Wiggle the headlight assembly out from the fender, being careful not to scratch the lens or the fender. There will still be some resistance because the assembly is retained by headlight assembly guide pins. These pins need to be popped out of their ball sockets to allow the assembly to detach.
Release the electrical connector going to the headlight. Lift up on the harness locks and then pull it from the headlight socket.
Twist the directional wire harness 1/4 turn to remove it from the assembly.
Place the assembly on a safe surface where it will not get scratched or damaged. Turn the retaining collar on the headlight 1/4 turn.
Remove the headlight. Wear latex gloves before handling the new headlight or your skin will damage the glass. Install the 9007 replacement bulb into the collar and then reverse the removal procedure to reassemble.
