Hi, my name is XXXXX XXXXX I have been in the home improvement and repair field for 20 years. I will be glad to help you today. First remove the coals, then if you look at the bars you will find right below them and at the top of the cover at the bottom, in the corners there are two screws. Remove the screws then remove the cover. Then remove the rotisserie and the bulbs are there behind that.
