  1. The KnightLight Concept Updated Feb 08 v3.0

  2. Developments in Automotive Forward - Lighting • Development and roll out of LED Forward - Lighting. The Lexus LS600 was 1st to market in 07 with Lo beam (Koito + Nichia); Audi R8 2nd to market, but with both Lo & Hi beam (A-L + Philips Lumiled) Cadillac Escalade Platinum due July 08, with Lo beam converting to Hi beam (Hella + Osram Opto) • Adaptive Front-Lighting System (AFS) - return to Steering the Headlight beams. Automatic modifying of the beam pattern in response to vehicle speed, weather conditions and road situations providing improved driving safety at night • More creative lighting designs possible - Meets the desire for linear and other arrays to replace circular headlamps The KnightLight patent portfolio covers the combination of LEDs with dynamic AFS for any headlight design - past, present and future Page 2

  3. Light Emitting Diodes (LEDs) Benefits over conventional automotive bulbs LEDs are the future of automotive lighting Page 3

  4. Haitz’s Law Haitz’s Law is the LED corollary to Moore’s Law of semiconductors. Named after Roland Haitz (now retired of Agilent Technologies) the Law forecasts that: “Every 10 years the amount of light generated by an LED increases by a factor of 20, while the cost of per lumen (unit of usable light emitted) falls by a factor of 10”. Haitz’s Law suggests all lighting, including Automotive Forward-Lighting, should become LEDs within a decade. LED technology is here to stay Page 4

  5. KnightLight Patents combine LEDs & AFS GB 2 362 207 priority date 26th Sept 98. Granted 24th July 02. ‘Automated Lighting’. Claim 1. ‘Automated lighting having a source of light formed by a plurality of white light emitting diodes pivotably mounted on a support member so that they are adjustable to change the angle and / or shape of the light beam produced by the diodes’. The UK Pat Office defined ‘Automated’ from the dictionary as: ‘with little or no human intervention’. Angle is beam direction, as in levelling and steering, shape is zoom or beam width. US 7 004 603 priority date 7th April 00. Granted 28th Feb 06. ‘Angle Adjustment Device’. Claim 1. ‘Automated lighting having a source of light formed by a plurality of light emitting diodes (LEDs) that are pivotably mounted on a support member with a universal joint so that said LEDs are adjustable to change at least one of an angle and a shape of a light beam produced by said LEDs’. Claim 19. ‘Automated lighting having a source of light formed by a plurality of light emitting diodes (LEDs) that are pivotably mounted on a support’. Application for Continuation in Part (C-in-P)US 11/240,096, filed 30th Sept 05, published as 2006/0023461 2nd Feb 06. Expands upon the KnightLight technique specific to automotive LED AFS. The US Examiner, in a preliminary review April 07, viewed this as two inventions and requested a split. Application for Divisional of C-in-P filed 31st Oct 07. This filing reopens the patent string and allows for further Continuations and International filings. Under Patent rules there is a time frame to be adhered to and cooperation between KL and the Master Licensee would maximise the additional coverage from future filings to the benefit both parties.

  6. KnightLight Concept - Features & Benefits • A unique Beam Angle Adjustment technique providing combined automated levelling, steering and lensless zoom for improved safety and vision. Controls all movements of the LED beams and is independent of the construction of the light source photometric requirements. The individual LEDs or arrays making up the whole pivot relative to the Front Plate. This allows for the Front Plate to be as far forward in the vehicle as possible and has two consequences. Firstly, the light is not masked when automatically levelled or steered. Secondly, with vehicle designs with curved front ends, the outer beam on a corner can pivot further, before being masked by the nose of the vehicle. • Flexible and adaptable allowing phased introduction of automated self levelling and dynamic beam steering • Capability to fit onto any vehicle - past, present and future • Where static bending light is not an option this is the only practical solution for dynamic levelling and steering of arrays • When legislation allows zoom capability can be included The KnightLight technique provides the best way to exploit the benefits of LEDs and AFS for any LED array Page 6

  10. KnightLight Concept - Design Opportunities The KnightLight technique is suitable for any LED array, therefore maximising design opportunities and capability for differentiation. Futuristic Avant-Garde Technical Contemporary Freedom to create eye catching designs: Brand differentiation through Design Technical, Organic, Innovative, Avant-Garde Technical Organic Page 10

  11. How can KnightLight help you? • KL is a patented technique that can be applied to any headlight design • KL can grant a Master Licence for its patented technology helping you secure the future in automotive lighting. There is significant potential for sub licensing. • KL patents provide the Master Licensee with an opportunity to secure competitive advantage through maximising “divisional” patent opportunities of future filings (but there is a time limit to achieve this) • KL can provide know how to help develop and implement its concept • KL can provide an alternative perspective to automotive lighting through its knowledge of creative lighting in the Entertainment industry KnightLight - The Right Light in the Right Place at the Right Time Page 11
