Isuzu ascender How do you replace the headlight bulbs?

After 2 days of screwing with mine here is what I found: Open the hood There are 2 clips on top of the headlamp unit. Lift them. Pull the headlamp unit away from the vehicle. In back of the head lamp you will see a small round cover. Remove that cover and you should have access to the bulbs. Disconnect the wiring harness from the bulb. Remove the headlamp bulb by turning the socket counter clockwise. Install the replacement bulb by turning it clockwise. Re-assemble the headlamp.
