We have just designed a new LED harness that has white LED's in the front and red LED's to the rear, we designed it for the construction industry who wanted to be able to highlight the presence of a worker in low light conditions AND also understand which way that worker was facing.
To an obsever operating plant or machinery having an appreciation of whether a worker is aware of your presence is an important safety consideration, and with LED's that outperform everything we have seen so far used on hi-vis tabards we believe we have a product that offers improved site safety.
Furthermore it uses a rechargeable battery, comes supplied with a USB connector, is fully adjustable and allows you to retain your current PPE as it will go over the top of it. Makes a great cycling light too!!
