Adaptive motorcycle cornering headlights

There is no need to buy an expensive BMW or KTM motorcycle to have headlights that illuminate the inside of a corner.

American lighting company of Wisconsin, J.W. Speaker Corporation, has released the world’s first aftermarket motorcycle headlight that fills in the dark void of a corner.

The headlights are now imported to Australia by Invision Sales at $1200 for the 8790A 7-inch model and $999 for the 8690A 6-inch version. They are available at Autobarn, Supercheap and Burson, and the importers will soon have them available in some motorcycle shops.

They use sensors to calculate bank angles up to 30 degrees and automatically direct a light array angling up or down in the foreground as the motorcycle leans.

The headlight also “tunes” the low beam and banking optics in a way that maximises visibility in corners.

Over 30 degrees the light is still there, but it doesn’t intensify any more.

J.W. Speaker co-president Tim Speaker says the light solves a fundamental problem of night-time visibility that current aftermarket and OEM motorcycle headlights are not able to address.

The unit is designed to “plug and play” into many styles of motorcycle via a H4 connector and the position light via a flying lead.

However, he says the LED lighting innovation is also being considered by motorcycle manufacturers for inclusion in upcoming models.

The Model 8790 adaptive headlight platform features J.W. Speaker’s innovative low-beam solid-optic technology and ComfortLite high beam.

The light has a fully legal symmetrical beam pattern which is approved for DOT, SAE and ECE.

The outer lens is made of clear polycarbonate and the rear housing is die cast aluminium. It is available in black and chrome internal finish.

The lamp has ECE 113 approval which means it is compliant for use in Australia as ADR or CRN are no longer require if the product has ECE approval.

The lamps will fit any motorbike with 7” or 5 3/4″ housing. Some Harely-Davidson motorcycles may require an adaptive ring which is also available.
