<p>The Bright Bolt (2) as shown in illustration 'A' has, in each of the facets of its hexagonally shaped head a reflective device (8) which fits flush into a countersunk or drilled hole. The stem of the Bright Bolt has a thread which can allow for a securing nut (14) to be tightened into position. The reflective power of the Bright Bolt can be enhanced with the fitting of its own capping hood (4) which is domed in shape and has its own reflective coating (16) and is push fitted onto the head of the bolt (2) allowing the head to slot into the moulded 'Well' (10) and is secured to the bolt (2) by its own moulded washer attachment (6) which slips over the stem of the bolt (2). In illustration 'B' the Bright Bolt (2) can be hollowed as shown to allow for a small light bulb (7) to be installed and to be fed by a continuous electrical feed or supply (3).</p> |
