Such a tiny space to work with... Twisting the bulb was easier when it was unplugged first. Because of recessed space and new LED bulb has cords and circuitboard dangling, inserting it was also difficult. I tried to connect the new bulb, tuck in the loose stuff and then insert new bulb in place, but found it to be almost impossible. So instead, I insert the new bulb and secured it first, then connected the circuit, then tucked in the loose assembly inside... It worked! Thanks Rich06!
So here's summary. I purchased the
Amazon 9005 HB3 LED bulbs.
1) disconnect the bulb connection
2) twist the bulb counterclockwise to remove
3) insert new bulb in place, turn clockwise to secure (make sure the 90deg bend points downward, same as original bulb)
4) make circuit connection to the new bulb
5) tuck in the circuit module and wires attached to the led bulb
6) close the outside cover
