The front light units are designed for backdating: converting an impact bumper car to the earlier pre-1973 shape. The lamp units fix directly to impact-bumper front wings and are moulded to accept pre-impact sidelight and indicator lenses. There is also an air intake moulded into the horn grille section, which some backdaters building ST- or RSR-style 911s have used to feed cold air to oil coolers mounted in the front corners.
Manufactured in non-rusting composite and finished in reflective white gelcoat, the EB backdate light units come with bulbs and bulbholders. The parts can be painted body colour and fitted as a simple addition, or fixed to the wing with gaps filled and the complete wing painted. They are shaped to match other EB backdate parts, including matching bonnet and a choice of front bumpers.
