I love three brush generators; they are so simple. However, the concept seems to freak people out these days. Tighten up the cover band sufficiently that it will stay in place, but can slide back to reveal the cutouts in gene case. Then, when darkness is approaching, and you're still out on the road, it is easy to pull off the road, open hood, slide back cover, move brush down, slide cover back, close hood, and carry on driving. Takes longer for me to type it than to perform it. You don't even need to switch off the engine!

Once you become familiar with the two positions you'll need to position the brush, you'll be able to do it blindfolded!
