Today I was performing my weekly clean on our Harman XXV and had a flashlight. My son came upstairs and said Dad would you like to borrow my LED headlamp I use for fishing at night. I said sure. Wow what a difference the headlamp made, plus I now had both hands free to do whatever. Wanted to share this idea with you as it makes it so much easier to work on unit and lights the insides up very bright.
