I have a heath-zenith secure home motion activated light model SH-5598-WH light and the bulb is burnt out and I can't figure out how to change it...no manual.....it takes a 100 watt halogen plug in llight......help! Also, if you answer this how do I know your answer, do I just keep checking for your comment along with all the others or do you email me? (dnclon@iwon.com) Thanks in advance!
