NOTHING is as annoying as a blown lightbulb, trying to pull it out in a vehicle that's at first in an almost impossible spot, and then - you turn the lighter Squeeze the lightbulb and suddenly it explodes! - This little tool saved me A LOT of pain when trying to change the lightbulbs in my 2003 Corvette vanity mirrors - no blown lightbulbs - no colorful expressions etc great little tool!
