Light up your next construction-themed event, groundbreaking ceremony, or job fair with our Yellow Construction Hat LED Keychain. Each light up yellow keychain comes with a bright white LED to light the way wherever you are, and a 2" keychain so it's always accessible. The yellow construction hat on your light up yellow keychain measures 2 ¾" top to bottom and 1 ¼" wide, and is just under an inch tall. Each Yellow Construction Hat LED Keychain comes with batteries included and installed. Our Yellow Construction Hat LED Keychain is sold by the piece. Please Note, the shades of the product color may vary slightly since we might need to use different dye lots on orders of large quantities.
