Our CAUTION WATCH FOR FORKLIFT backlit LED sign features a block-style message that is readable even when the sign is turned off. When illuminated, the bright LEDs illuminate the sign face to optimize readability in low light conditions. Choose your voltage, 120-277VAC or 12-24VDC. Our signs can be controlled by a switch which can be found on our website or by a third-party relay or sensor. This sign comes standard with our Lift n' Shift back which allows for easy wall mounting that doesn't require additional mounting. If you require extra mounting options, we also offer ceiling, side and recess mounting brackets.
